Product Overview
The OPA4197 is a Texas Instruments quad precision operational amplifier for Signal_Chain designs requiring four amplifier channels in one device. Recommended operation covers ±2.25 V to ±18 V dual supply, or 4.5 V to 36 V single supply, with a -40°C to +125°C operating temperature range.
Precision parameters include input offset voltage ratings of ±25 µV typical and ±100 µV maximum at VS = ±18 V, TA = 25°C, and ±10 µV typical and ±100 µV maximum near the positive rail condition. Offset drift is specified across -40°C to +125°C, with typical values of ±0.5 µV/°C and ±0.8 µV/°C depending on common-mode condition.
Dynamic and drive specifications include 10 MHz gain bandwidth product, 20 V/µs slew rate, ±65 mA output current, and capacitive load drive up to 1 nF. Assembly options are 14-pin SOIC (D) at 8.65 mm x 3.90 mm and 14-pin TSSOP (PW) at 5.00 mm x 4.40 mm, with package thermal resistance values of 86.4°C/W and 92.6°C/W respectively.
