The AD9201 is a complete dual channel, 20 MSPS, 10-bit CMOS ADC. It is optimized specifically for applications where close matching between two ADCs is required (e.g., I/Q channels in communications applications). The 20 MHz sampling rate and wide input bandwidth will cover both na
The AD9201 is a dual‑channel, 20 MSPS, 10‑bit CMOS ADC optimized for applications requiring closely matched I and Q channels. It integrates on‑chip analog input buffers, a bandgap reference, and a multiplexed digital output bus, eliminating the need for external input amplifiers in most designs.
The datasheet provides full electrical specifications, pin‑out tables, absolute maximum ratings, typical performance curves, and theory of operation. It also includes package dimensions for the 28‑lead SSOP form factor and guidelines for power supply and reference configuration.
