LTC1278-5CSW#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1278-5CSW#TRPBF is a 12-bit, 500ksps sampling analog-to-digital converter (ADC) in a 24-lead SOIC package. It operates from a single 5V or ±5V supply, consuming 75mW during conversion and 8.5mW in shutdown mode. Key specifications include ±1LSB INL/DNL, 70dB S/(N+D), and 78dB THD at 100kHz input. The device features an internal synchronized clock, a 200ns sample-and-hold, and a precision 2.42V reference. It supports unipolar (0V to 5V) and bipolar (±2.5V) input ranges with a flexible parallel interface for DSPs.
