Feature Description (continued)

7.3.3 Input Offset Voltage and Input Offset Voltage Drift

The TLVx376 family of operational amplifiers is manufactured using TI's e-trim™ technology. Each amplifier is

trimmed in production, thereby minimizing errors associated with input offset voltage and input offset voltage drift.

The e-trim™ technology is a TI proprietary method of trimming internal device parameters during either wafer

probing or final testing.

The TLVx376 in a unity-gain configuration can directly drive up to 250 pF of pure capacitive load. Increasing the

gain enhances the ability of the amplifier to drive greater capacitive loads; see Figure 16. In unity-gain

configurations, capacitive load drive can be improved by inserting a small (10

with the output, as shown in Figure 22. This resistor significantly reduces ringing and maintains dc performance

for purely capacitive loads. However, if there is a resistive load in parallel with the capacitive load, a voltage

divider is created, introducing a gain error at the output and slightly reducing the output swing. The error

7.3.4 Common-Mode Voltage Range

The input common-mode voltage range of the TLVx376 series extends 100 mV beyond the supply rails. The

offset voltage of the amplifier is very low, from approximately (V–) to (V+) – 1 V, as shown in Figure 23. The

offset voltage increases when common-mode voltage exceeds (V+) –1 V. Common-mode rejection is specified

from (V–) to (V+) – 1.3 V.
