Overview
The LTC2311HMSE-12#PBF from Analog Devices Inc. is a high-performance, 12-bit + sign successive approximation register (SAR) analog-to-digital converter (ADC). This device is designed for applications requiring a wide dynamic range and high common mode rejection. It operates from a single 3.3V or 5V supply and features differential inputs with an 8VP-P differential input range. The LTC2311-12 is notable for its low noise, high speed, and precision, achieving ±0.25LSB INL typical and 73dB SNR typical. It also includes an onboard low drift (20ppm/°C max) 4.096V temperature-compensated reference and supports high-speed SPI-compatible serial interfaces with CMOS or LVDS options.
