TLC2252QD

Instrumentation, Op Amps, Buffer Amps Overview

The TLC2252QD is a dual-channel operational amplifier from the Advanced LinCMOS family, designed for very low-power applications. It features rail-to-rail output performance and operates within a supply voltage range of ±2.2 V to ±8 V (4.4 V to 16 V total). The device provides a gain-bandwidth product of 0.2 MHz and a slew rate of 0.12 V/µs. Key electrical characteristics include an input bias current of 60 pA, an input offset voltage of 1500 µV maximum at 25°C, and a typical noise density of 19 nV/√Hz at 1 kHz. It functions in an industrial temperature range of -40°C to 125°C.
