Overview
The TLV379IDR, part of the TLV379 family, is a cost-optimized, low-voltage, micropower operational amplifier produced by Texas Instruments. This single operational amplifier is designed for power-sensitive applications and operates on a supply voltage as low as 1.8 V (±0.9 V) with an extremely low quiescent current of 4 µA per channel. The TLV379IDR features rail-to-rail input and output capability, making it suitable for virtually any single-supply application. It is available in 5-pin SC70 and SOT-23 packages, as well as an 8-pin SOIC package, and is specified from –40°C to +125°C.
