3 Description
The TLV379 family of single, dual, and quad operational amplifiers represents a cost-optimized generation of low-voltage and micropower amplifiers. Operating on a supply voltage as low as 1.8 V (±0.9 V) and consuming extremely low quiescent current of 4 µA per channel, these amplifiers are wellsuited for power-sensitive applications. In addition, the rail-to-rail input and output capability allows the TLV379 family to be used in virtually any singlesupply application.
The TLV379 (single) is available in 5-pin SC70 and SOT23, and 8-pin SOIC packages. The TLV2379 (dual) comes in an 8-pin SOIC package. The TLV4379 (quad) is offered in a 14-pin TSSOP package. All versions are specified from –40°C to +125°C.
