LTC2311IMSE-12#WTRPBF

Analog To Digital Converters (ADC) Overview

The LTC2311IMSE-12#WTRPBF is a 12-bit + sign successive approximation register (SAR) analog-to-digital converter with differential inputs and a wide input common mode range. It operates from a single 3.3V or 5V supply, providing an 8VP-P differential input range. The device achieves ±0.25LSB typical integral nonlinearity (INL), guaranteed 12-bit resolution without missing codes, and 73dB typical signal-to-noise ratio (SNR). It features a low drift internal reference (20ppm/°C max), SPI-compatible serial interface supporting CMOS or LVDS logic, and dissipates 50mW at 5V. The component is AEC-Q100 qualified for automotive applications and housed in a 16-lead MSOP package.
