GENERAL DESCRIPTION

The AD9763/AD9765/AD9767 are dual-port, high speed, 2-channel, 10-/12-/14-bit CMOS DACs. Each part integrates two high quality TxDAC+? cores, a voltage reference, and digital interface circuitry into a small 48-lead LQFP. The AD9763/AD9765/AD9767 offer exceptional ac and dc performance while supporting update rates of up to 125 MSPS.
