LTC2311-12/-14/-16 5Msps Differential Input ADCs Analog Devices Inc. LTC2311-12/-14/-16 5Msps Differential Input ADCs are successive approximation register (SAR) ADCs with differential inputs and wide input common-mode ranges. The LTC2311-12/-14/-16 operates from 3.3V or 5V supplies and feature an 8VP-P differential input range. This makes the Analog Devices ADCs ideal for applications that require a wide dynamic range with high common-mode rejection.
