Analog Devices Inc. AD9773BSVZ

Description
The AD9773 is a 12-bit, 160 MSPS dual TXDAC D/A converter with selectable 2x/4x/8x interpolating filters. It features programmable channel gain and offset adjustment, digital quadrature modulation capability, and a direct IF transmission mode for IFs above 70 MHz. The AD9773 is fully compatible with the SPI port and offers excellent AC performance, including an SFDR of -69 dBc from 2 MHz to 35 MHz and a WCDMA ACPR of -69 dB at an IF of 19.2 MHz.
