The AD9201 is a complete dual channel, 20 MSPS, 10-bit CMOS ADC. The AD9201 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 narrow- band and spread-spectrum channels. The AD9201 integrates two 10-bit, 20 MSPS ADCs, two input buffer amplifiers, an internal voltage reference and multiplexed digital output buffers.
Each ADC incorporates a simultaneous sampling sample-and-hold amplifier at its input. The analog inputs are buffered; no external input buffer op amp will be required in most applications. The ADCs are implemented using a multistage pipeline architecture that offers accurate performance and guarantees no
missing codes. The outputs of the ADCs are ported to a multiplexed digital output buffer. The AD9201 is manufactured on an advanced low cost CMOS
process, operates from a single supply from 2.7 V to 5.5 V, and consumes 215 mW of power (on 3 V supply). The AD9201 input structure accepts either single-ended or differential signals, providing excellent dynamic performance up to and beyond its 10 MHz Nyquist input frequencies.
