Product Overview
The OPA2197 is a Texas Instruments dual precision operational amplifier for Signal_Chain designs that require two amplifier channels in one device. It operates from ±2.25 V to ±18 V dual supplies or 4.5 V to 36 V single supplies, with absolute maximum supply ratings of ±20 V or 40 V single supply.
Precision specifications include input offset voltage ratings of ±25 µV typical and ±100 µV maximum at VS=±18 V, TA=25°C, and ±10 µV typical with ±100 µV maximum at VCM=(V+)–1.5 V. Offset voltage drift is specified across -40°C to +125°C, with separate limits for VCM=(V+)–3 V and VCM=(V+)–1.5 V conditions.
Dynamic and drive parameters include 10 MHz gain bandwidth product, 20 V/µs slew rate, ±65 mA output current, and capacitive load drive up to 1 nF. The device draws 1 mA typical quiescent current per amplifier and provides 120 dB minimum common-mode rejection.
Package options for OPA2197 include SOIC-8 at 4.90 mm x 3.90 mm and VSSOP-8 at 3.00 mm x 3.00 mm. Thermal resistance is 107.9°C/W for the D SOIC-8 package and 158°C/W for the DGK VSSOP-8 package.
