Overview
The OPA170AIDBVT is a part of the OPAx170 family of operational amplifiers produced by Texas Instruments. This device is a 36-V, single-supply, low-noise operational amplifier that features a wide supply voltage range from 2.7 V to 36 V (±1.35 V to ±18 V). It is designed to offer low noise, high common-mode rejection, and low quiescent current, making it suitable for a variety of applications. The OPA170AIDBVT is available in the DBV package, which is a 5-pin SOT-23 package, providing a compact solution for space-constrained designs.
