It consumes only 11 µA (typ) of supply current and is ideal for battery-power applications. Looking at Figure 1, the TLV2711 has a 3-V noise level of 21 nV/√Hz at 1kHz; five times lower than competitive SOT-23 micropower solutions. The device exhibits rail-to-rail output performance for increased dynamic range in single- or split-supply applications. The TLV2711 is fully characterized at 3 V and 5 V and is optimized for low-voltage applications. V n – Equivalent Input Noise Voltage – nV/ Hz 80 The TLV2711, exhibiting high input impedance and low noise, is excellent for small-signal conditioning for 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).

This ultra-small package allows designers to place single amplifiers very close to the signal source, minimizing noise pick-up from long PCB traces. TLV2711Y chip information This chip, when properly assembled, displays characteristics similar to the TLV2711C. Thermal compression or ultrasonic bonding may be used on the doped-aluminum bonding pads. This chip may be mounted with conductive epoxy or a gold-silicon preform.

Figure 50 and Figure 51 illustrate its ability to drive loads up to 600 pF while maintaining good gain and phase margins (Rnull = 0). A smaller series resistor (Rnull) at the output of the device (see Figure 53) improves the gain and phase margins when driving large capacitive loads. Figure 50 and Figure 51 show the effects of adding series resistances of 500 Ω and 1000 Ω. The addition of this series resistor has two effects: the first is that it adds a zero to the transfer function and the second 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 improvement in phase margin, equation 1 can be used. ǒ Ǔ + tan–1 2 × π × UGBW × Rnull × CL where : ∆φ m1 + improvement in phase margin UGBW + unity-gain bandwidth frequency R null + output series resistance C L + load capacitance ∆φ m1 24 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 (1) TLV2711, TLV2711Y Advanced LinCMOS RAIL-TO-RAIL MICROPOWER SINGLE OPERATIONAL AMPLIFIERS SLOS196 – AUGUST 1997 APPLICATION INFORMATION driving large capacitive loads (continued) The unity-gain bandwidth (UGBW) frequency decreases as the capacitive load increases (see Figure 52).

Series-Resistance Circuit driving heavy dc loads The TLV2711 is designed to provide better sinking and sourcing output currents than earlier CMOS rail-to-rail output devices. This device is specified to sink 500 µA and source 250 µA at VDD = 3 V and VDD = 5 V at a maximum quiescent IDD of 25 µA. This provides a greater than 90% power efficiency. When driving heavy dc loads, such as 10 kΩ, the positive edge under slewing conditions can experience some distortion. This condition can be seen in Figure 38. This condition is affected by three factors. D D D Where the load is referenced. When the load is referenced to either rail, this condition does not occur. The distortion occurs only when the output signal swings through the point where the load is referenced. Figure 39 illustrates two 10-kΩ load conditions. The first load condition shows the distortion seen for a 10-kΩ load tied to 2.5 V. The third load condition shows no distortion for a 10-kΩ load tied to 0 V. Load resistance. As the load resistance increases, the distortion seen on the output decreases. Figure 39 illustrates the difference seen on the output for a 10-kΩ load and a 100-kΩ load with both tied to 2.5 V.
