LTC2321HUFD-16#PBF

Analog To Digital Converters (ADC) Overview

The LTC2321HUFD-16#PBF is a dual-channel, 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices Inc. It operates from a single 3.3V or 5V supply and supports a sampling rate of 2Msps per channel with no cycle latency. The device features differential inputs with an 8V P-P range and wide common mode capability. It includes an onboard low-drift temperature-compensated reference (2.048V or 4.096V). Electrical performance guarantees 16-bit resolution without missing codes, ±4LSB typical integral nonlinearity, and 81dB SNR at 500kHz input frequency. Power consumption is 31mW per channel, reducible via nap and sleep modes.
