Overview
The AD9214BRSZ-80 is a 10-bit monolithic sampling analog-to-digital converter (ADC) produced by Analog Devices Inc. This device is optimized for low cost, low power, small size, and ease of use. It operates up to 80 MSPS conversion rate and features an on-chip track-and-hold circuit. The AD9214BRSZ-80 is designed to provide outstanding dynamic performance over its full operating range and requires only a single 3.3 V power supply (operating range of 2.7 V to 3.6 V) for full performance operation.
