Analog Devices Inc. AD7389-4 16-Bit SAR Analog-to-Digital Converters

Analog Devices Inc. AD7389-4 16-Bit SAR Analog-to-Digital Converters is a simultaneous sampling ADC that operates from a 3.0V to 3.6V power supply. The AD7389-4 features throughput rates up to 2 MSPS. The analog input type is differential, accepts a wide common-mode input voltage, and the analog inputs are sampled and converted on the falling edge of CS.
