AD9058

a FEATURES 2 Matched ADCs on Single Chip 50 MSPS Conversion Speed On-Board Voltage Reference Low Power (<1 W) Low Input Capacitance (10 pF) 65 V Power Supplies Flexible Input Range APPLICATIONS Quadrature Demodulation for Communications Digital Oscilloscopes Electronic Warfare Radar GENERAL DESCRIPTION The AD9058 combines two independent, high performance, 8-bit analog-to-digital converters (ADCs) on a single monolithic IC. Combined with an optional on-board voltage reference, the AD9058 provides a cost-effective alternative for systems requiring two or more ADCs. Dynamic performance (SNR, ENOB) is optimized to provide up to 50 MSPS conversion rates. The unique architecture results in low input capacitance while maintaining high performance and low power (<0.5 W/channel). Digital inputs and outputs are TTL compatible. Performance has been optimized for an analog input of 2 V p-p (± 1 V; 0 V to 2 V). Using the on-board 2 V voltage reference, the AD9058 can be set up for unipolar positi...
