Product Overview
The OPA196 is a Texas Instruments single 36-V rail-to-rail operational amplifier for Signal_Chain designs. It supports recommended supply operation from 4.5 V to 36 V, or split supplies from ±2.25 V to ±18 V, with specifications across -40°C to +125°C.
Input characteristics include ±25 µV typical and ±100 µV maximum input offset voltage at VS=±18 V, ±5 pA typical input bias current at 25°C, and 15 nV/√Hz typical input voltage noise density at 1 kHz for the lower common-mode range. Common-mode input range extends from (V-) - 0.1 V to (V+) + 0.1 V.
Dynamic and output specifications include 2.5 MHz typical unity-gain bandwidth, 7.5 V/µs rising and 5.5 V/µs falling slew rate, 0.7 µs typical settling time to 0.01%, and 0.0012% THD+N at G=1, 1 kHz, and 3.5 VRMS. Package options include SOIC-8, SOT-5, and VSSOP-8 for assembly flexibility.
