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 well-

suited for power-sensitive applications. In addition,

the rail-to-rail input and output capability allows the

TLV379 family to be used in virtually any single-

supply 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.
