The TLV237xtakes the minimum operating supply voltage down to 2.7 V over the extended industrial temperature range whileadding the rail-to-rail output swing feature. The TLV237x also provides 3-MHz bandwidth from only 550 µA. Themaximum recommended supply voltage is 16 V, which allows the devices to be operated from (±8 V suppliesdown to ±1.35 V) a variety of rechargeable cells.The CMOS inputs enable use in high-impedance sensor interfaces, with the lower voltage operation makingan ideal alternative for the TLC227x in battery-powered applications. The rail-to-rail input stage furtherincreases its versatility. The TLV237x is the seventh member of a rapidly growing number of RRIO productsavailable from TI, and it is the first to allow operation up to 16-V rails with good ac performance.All members are available in PDIP and SOIC with the singles in the small SOT-23 package, duals in the MSOP,and quads in the TSSOP package.The 2.7-V operation makes the TLV237x compatible with Li-Ion powered systems and the operating supplyvoltage range of many micro-power microcontrollers available today including TI’s MSP430.SELECTION OF SIGNAL AMPLIFIER PRODUCTS†DEVICETLV237xTLC227xTLV27xTLC27xTLV246xTLV247xVDD (V)2.7−164−162.7−163−162.7−62.7−6VIO(µV)5003005001100150250Iq/Ch(µA)5501100550675550600725IIB (pA)1111130021GBW(MHz)32.231.76.42.81.8SR(V/µs)2.43.62.43.61.61.51.4SHUTDOWNYes———YesYes—RAIL-TO-RAILI/OOO—I/OI/OOSINGLES/DUALS/QUADSS/D/QD/QS/D/QS/D/QS/D/QS/D/QD/QTLV244x2.7−10300†Typical values measured at 5 V, 25°CPlease be aware that an important notice concerning availability, standard warranty, and use in critical applications ofTexasInstruments semiconductor products and disclaimers thereto appears at the end of this data sheet.PRODUCTION DATA information is current as of publication date.Products conform to specifications per the terms of Texas Instrumentsstandard warranty.

operationThe TLV237x input stage consists of two differential transistor pairs, NMOS and PMOS, that operate togetherto achieve rail-to-rail input operation. The transition point between these two pairs can be seen in Figures 1,2, and 3 for a 2.7-V, 5-V, and 15-V supply. As the common-mode input voltage approaches the positive supplyrail, the input pair switches from the PMOS differential pair to the NMOS differential pair. This transition occursapproximately 1.35 V from the positive rail and results in a change in offset voltage due to different devicecharacteristics between the NMOS and PMOS pairs. If the input signal to the device is large enough to swingbetween both rails, this transition results in a reduction in common-mode rejection ratio (CMRR). If the inputsignal does not swing between both rails, it is best to bias the signal in the region where only one input pair isactive. This is the region in Figures 1 through 3 where the offset voltage varies slightly across the input rangeand optimal CMRR can be achieved. This has the greatest impact when operating from a 2.7-V supply voltage.driving a capacitive loadWhen the amplifier is configured in this manner, capacitive loading directly on the output decreases the device’sphase margin leading to high frequency ringing or oscillations. Therefore, for capacitive loads of greater than10 pF, it is recommended that a resistor be placed in series (RNULL) with the output of the amplifier, as shownin Figure 33. A minimum value of 20 Ω should work well for most applications.RFInputRG−+VDD/2RNULLOutputCLOADFigure 33. Driving a Capacitive Loadoffset voltageThe output offset voltage, (VOO) is the sum of the input offset voltage (VIO) and both input bias currents (IIB) timesthe corresponding gains.

However, in the areas of the amplifier inputs andoutput, the ground plane can be removed to minimize the stray capacitance.capacitor on each supply terminal. It may be possible to share the tantalum among several amplifiersdepending on the application, but a 0.1-µF ceramic capacitor should always be used on the supply terminalof every amplifier. In addition, the 0.1-µF capacitor should be placed as close as possible to the supplyterminal. As this distance increases, the inductance in the connecting trace makes the capacitor lesseffective. The designer should strive for distances of less than 0.1 inches between the device powerterminals and the ceramic capacitors.will often lead to stability problems. Surface-mount packages soldered directly to the printed-circuit boardis the best implementation.DSockets—Sockets can be used but are not recommended. The additional lead inductance in the socket pinsDShort trace runs/compact part placements—Optimum high performance is achieved when stray seriesinductance has been minimized. To realize this, the circuit layout should be made as compact as possible,thereby minimizing the length of all trace runs. Particular attention should be paid to the inverting input ofthe amplifier. Its length should be kept as short as possible. This helps to minimize stray capacitance at theinput of the amplifier.DSurface-mount passive components—Using surface-mount passive components is recommended for highperformance amplifier circuits for several reasons. First, because of the extremely low lead inductance ofsurface-mount components, the problem with stray series inductance is greatly reduced. Second, the smallsize of surface-mount components naturally leads to a more compact layout thereby minimizing both strayinductance and capacitance. If leaded components are used, it is recommended that the lead lengths bekept as short as possible.shutdown functionThree members of the TLV237x family (TLV2370/3/5) have a shutdown terminal for conserving battery life inportable applications. When the shutdown terminal is tied low, the supply current is reduced to 25 µA/channel,the amplifier is disabled, and the outputs are placed in a high impedance mode. To enable the amplifier, theshutdown terminal can either be left floating or pulled high. When the shutdown terminal is left floating, careshould be taken to ensure that parasitic leakage current at the shutdown terminal does not inadvertently placethe operational amplifier into shutdown.16WWW.TI.COMPOST OFFICE BOX 1443 HOUSTON, TEXAS 77251−1443•TLV2370, TLV2371, TLV2372, TLV2373, TLV2374, TLV2375FAMILY OF 550ƵA/Ch 3ĆMHz RAILĆTOĆRAIL INPUT/OUTPUTOPERATIONAL AMPLIFIERS WITH SHUTDOWNSLOS270C − MARCH 2001 − REVISED DECEMBER 2003APPLICATION INFORMATIONgeneral power dissipation considerationsFor a given θJA, the maximum power dissipation is shown in Figure 37 and is calculated by the following formula:PWhere:D+ǒT–TMAXAqJAǓPD= Maximum power dissipation of TLV237x IC (watts)TMAX= Absolute maximum junction temperature (150°C)TA= Free-ambient air temperature (°C)θJA= θJC + θCAθJC= Thermal coefficient from junction to caseθCA= Thermal coefficient from case to ambient air (°C/W)MAXIMUM POWER DISSIPATIONvsFREE-AIR TEMPERATURE21.75Maximum Power Dissipation − W1.51.2510.750.50.25SOT-23 PackageLow-K Test PCBθJA = 324°C/WSOIC PackageLow-K Test PCBθJA = 176°C/WPDIP PackageLow-K Test PCBθJA = 104°C/WTJ = 150°CMSOP PackageLow-K Test PCBθJA = 260°C/W0−55−40−25−105203550658095110125TA − Free-Air Temperature − °CNOTE A:Results are with no air flow and using JEDEC Standard Low-K test PCB.Figure 37.
