Overview
The LTC2311IMSE-12#WPBF is a high-performance, 12-bit successive approximation register (SAR) analog-to-digital converter (ADC) produced by Analog Devices Inc. This device is designed for applications requiring low noise, high speed, and a wide input common mode range. Operating from a single 3.3V or 5V supply, it features differential inputs with an 8V peak-to-peak differential input range, making it ideal for applications that demand a wide dynamic range and high common mode rejection. The LTC2311-12 achieves high accuracy with ±0.25LSB INL typical and no missing codes at 12 bits, along with a 73dB signal-to-noise ratio (SNR) typical.
