Combined with an optional on-board voltage reference,the AD9058 provides a cost-effective alternative for systemsrequiring two or more ADCs. Dynamic performance (SNR, ENOB) is optimized to provide QUADRATURE RECEIVER up to 50 MSPS conversion rates. The unique architectureresults in low input capacitance while maintaining high per-formance and low power (<0.5 W/channel). Digital inputs G and outputs are TTL compatible. 8 Q Performance has been optimized for an analog input of 2 V p-p RF AD9058 ( 90 ±1 V; 0 V to 2 V). Using the on-board 2 V voltage reference, the AD9058 can be set up for unipolar positive operation 8
