Overview
The TLV379IDBVR, part of the TLV379 family, is a cost-optimized, low-voltage, micropower operational amplifier produced by Texas Instruments. This single-channel 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 TLV379IDBVR is available in a 5-pin SOT-23 package and is specified from –40°C to +125°C, making it suitable for a wide range of single-supply applications.
