Product Introduction

Overview

The TLC2272CD is a dual operational amplifier from Texas Instruments, part of the TLC227x family. These devices are known for their advanced LinCMOS technology, offering rail-to-rail output performance, which enhances the dynamic range in both single-supply and split-supply applications. The TLC2272 and its quadruple counterpart, TLC2274, provide high-speed performance with a bandwidth of 2 MHz and a slew rate of 3.6 V/µs, making them suitable for a wide range of applications requiring high-speed and low noise.

Applications

The TLC2272CD is ideal for various applications due to its high input impedance, low noise, and micropower dissipation levels. It is excellent for small-signal conditioning for high-impedance sources such as piezoelectric transducers. These devices are also suitable for hand-held monitoring and remote-sensing applications. Additionally, the rail-to-rail output feature makes them a great choice when interfacing with analog-to-digital converters (ADCs). They are also used in precision applications and as upgrades to the TLC27x in standard designs.
