3 Description
The TLV369 family of single and dual operational amplifiers represents a cost-optimized generation of 1.8-V nanopower amplifiers.
With the zero-crossover distortion circuitry, these amplifiers feature high linearity over the full common-mode input range with no crossover distortion, enabling true rail-to-rail input and operating from a 1.8-V to 5.5-V single supply. The family is also compatible with industry-standard nominal voltages of 3.0 V, 3.3 V, and 5.0 V.
The TLV369 (single version) is offered in a 5-pin SC70 package. The TLV2369 (dual version) comes in 8-pin VSSOP and SOIC packages.
