AD9201ARSZ

AD9201 is a complete dual channel, 20MSPS, 10bit 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 20MHz sampling rate and wide input bandwidth will cover both narrowband and spread-spectrum channels. Each ADC incorporates a simultaneous sampling sample-and-hold amplifier at its input. The analogue inputs are buffered; no external input buffer op-amp will be required in most applications. The ADC is implemented using a multistage pipeline architecture that offers accurate performance and guarantees no missing codes. The outputs of the ADC is ported to a multiplexed digital output buffer. It is manufactured on an advanced low cost CMOS process, operates from a single supply from 2.7V to 5.5V, and consumes 215mW of power (on 3V supply).
