Product Overview
The OPA2187 is a Texas Instruments dual zero-drift operational amplifier in the Signal_Chain category. It integrates two amplifier channels and is specified for low input offset voltage, with ±1 µV typical and ±10 µV maximum offset under the listed 25°C high-voltage test condition. Offset drift is specified at ±0.001 µV/°C typical and ±0.015 µV/°C maximum across -40°C to +125°C.
The device operates from a recommended 4.5 V to 36 V single supply or ±2.25 V to ±18 V dual supplies. Its common-mode voltage range is specified from (V-) - 0.1 V minimum to (V+) - 2 V maximum, and output swing is listed within 5 mV of the rails for high-impedance loads.
Package options include 8-pin SOIC (D) measuring 4.90 mm x 3.91 mm and 8-pin VSSOP (DGK) measuring 3.00 mm x 3.00 mm. Thermal data includes RθJA values of 159°C/W for VSSOP and 100.1°C/W for SOIC, supporting package-level assembly review.
