Texas Instruments OPA187IDR Zero-Drift Precision Operational Amplifier 8-SOIC 1 PC
$3.95
Genuine Texas Instruments OPA187IDR precision zero-drift operational amplifier supplied as one individual NOS IC. The OPA187 is a single-channel precision op amp designed for applications requiring extremely low input offset voltage, very low offset drift, low noise, and high DC accuracy.
Its zero-drift architecture continuously corrects input offset errors, making the device well suited for precision measurement, sensor interfaces, instrumentation, data acquisition, industrial control, bridge amplifiers, current sensing, precision filtering, and other low-level analog signal applications.

The original Digi-Key distributor packaging identifies Texas Instruments as the manufacturer and OPA187IDR as the manufacturer part number.
HISTORICAL BACKGROUND:
The OPA187 belongs to Texas Instruments' modern generation of zero-drift precision operational amplifiers developed for circuits where conventional op-amp offset voltage and temperature drift can become significant sources of measurement error.
Zero-drift amplifiers use internal correction techniques to continuously reduce DC offset and offset variation over temperature. This architecture became increasingly important in precision industrial instrumentation, sensor conditioning, medical equipment, test systems, data-acquisition hardware, current monitoring, and other applications that must accurately amplify very small signals.
The OPA187 remains an active production precision amplifier and continues to be used in new designs as well as repair and replacement applications.
