LTC1282ACSW#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1282ACSW#TRPBF is a 140ksps, 12-bit sampling A/D converter featuring an internal reference and clock. It operates from a single 3V or dual ±3V supply with typical power dissipation of 12mW. The device provides unipolar (0V to 2.5V) or bipolar (±1.25V) input ranges using LTBiCMOS switched capacitor technology. Maximum DC specifications include ±0.5LSB INL and ±0.75LSB DNL for the A grade. AC performance reaches 69dB S/(N + D) and 77dB THD at the Nyquist frequency of 70kHz. It utilizes a high-speed parallel interface.
