It offers 2 MHz of bandwidth and 1.6 V/µs of slew rate for applications requiring good ac performance. The device exhibits rail-to-rail output performance for increased dynamic range in single or split supply applications. The TLV2731 is fully characterized at 3 V and 5 V and is optimized for low-voltage applications. The TLV2731, exhibiting high input impedance and low noise, is excellent for small-signal conditioning of high-impedance sources, such as piezoelectric transducers. Because of the micropower dissipation levels combined with 3-V operation, these devices work well in hand-held monitoring and remote-sensing applications. In addition, the rail-to-rail output feature with single- or split-supplies makes this family a great choice when interfacing with analog-to-digital converters (ADCs). The device can also drive 600-Ω loads for telecom applications. With a total area of 5.6mm2, the SOT-23 package only requires one-third the board space of the standard 8-pin SOIC package. This ultra-small package allows designers to place single amplifiers very close to the signal source, minimizing noise pick-up from long PCB traces.

TLV2731, TLV2731Y Advanced LinCMOS RAIL-TO-RAIL LOW-POWER SINGLE OPERATIONAL AMPLIFIERS SLOS198A – AUGUST 1997 – REVISED MARCH 2001 APPLICATION INFORMATION driving large capacitive loads The TLV2731 is designed to drive larger capacitive loads than most CMOS operational amplifiers. Figure 49 through Figure 54 illustrate its ability to drive loads greater than 100 pF while maintaining good gain and phase margins (R = 0). null A small series resistor (R ) at the output of the device (see Figure 55) improves the gain and phase margins null when driving large capacitive loads. Figure 49 through Figure 52 show the effects of adding series resistances of 50 Ω, 100 Ω, 500 Ω, and 1000 Ω. The addition of this series resistor has two effects: the first effect is that it adds a zero to the transfer function and the second effect is that it reduces the frequency of the pole associated with the output load in the transfer function. The zero introduced to the transfer function is equal to the series resistance times the load capacitance. To calculate the approximate improvement in phase margin, equation 1 can be used. ∆φm1(cid:0)tan–1 (cid:1)2 × π × UGBW × Rnull × CL(cid:2) (1) Where: ∆φm1(cid:0)Improvement in phase margin UGBW (cid:0) Unity-gain bandwidth frequency Rnull (cid:0) Output series resistance CL (cid:0) Load capacitance The unity-gain bandwidth (UGBW) frequency decreases as the capacitive load increases (see Figure 53 and Figure 54). To use equation 1, UGBW must be approximated from Figure 53 and Figure 54. VDD+ VI – Rnull + CL VDD–/GND RL Figure 55. Series-Resistance Circuit POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 25
