Overview
The LTC2311IMSE-16#WPBF, produced by Analog Devices Inc., is a high-performance 16-bit successive approximation register (SAR) analog-to-digital converter (ADC). This device is characterized by its low noise, high speed, and wide input common mode range, making it ideal for applications requiring a wide dynamic range and high common mode rejection.
Operating from a single 3.3V or 5V supply, the LTC2311-16 features an 8V peak-to-peak differential input range. It achieves ±3LSB INL typical, with no missing codes at 16 bits and an 81dB signal-to-noise ratio (SNR) typical. The ADC includes an onboard low drift (20ppm/°C max) 2.048V or 4.096V temperature-compensated reference and supports an external 1.25V buffered reference input.
