LTC1400CS8#PBF

Analog To Digital Converters (ADC) Overview

The LTC1400CS8#PBF is a complete 12-bit, 400ksps successive approximation register (SAR) analog-to-digital converter in an 8-lead SOIC package. It integrates a 200ns sample-and-hold circuit and a precision 2.42V internal reference. The device operates from a single 5V supply for unipolar inputs (0V to 4.096V) or ±5V supplies for bipolar inputs (±2.048V). Key electrical specifications include ±1LSB INL/DNL, 75mW typical power dissipation at full speed, and a 3-wire serial interface compatible with DSPs and microcontrollers.
