Overview
The OPA2171AIDCUT is a part of the OPAx171 family of operational amplifiers produced by Texas Instruments. These devices are designed for general-purpose applications and offer high overall performance. They are single-supply operational amplifiers that can operate on a wide range of supply voltages from 2.7V to 36V (±1.35V to ±18V), making them versatile for various power supply conditions. The OPA2171AIDCUT is available in dual versions, providing two independent operational amplifiers in a single package, which enhances design flexibility and reduces component count.
