The AD9751 is a dual muxed port, ultrahigh speed, single-channel, 10-bit CMOS DAC. It integrates a high quality 10-bit TxDAC+ core, a voltage reference, and digital interface circuitry into a small 48-lead LQFP package. The AD9751 offers exceptional ac and dc performance while supporting update rates up to 300 MSPS.

The AD9751 has been optimized for ultrahigh speed applications up to 300 MSPS where data rates exceed those possible on a single data interface port DAC. The digital interface consists of two buffered latches as well as control logic. These latches can be time multiplexed to the high speed DAC in several ways. This PLL drives the DAC latch at twice the speed of the externally applied clock and is able to interleave the data from the two input channels. The resulting output data rate is twice that of the two input channels. With the PLL disabled, an external 2× clock may be supplied and divided by two internally.

The CLK inputs (CLK+/CLK–) can be driven either differentially or single-ended, with a signal swing as low as 1 V_P-P.

The DAC utilizes a segmented current source architecture combined with a proprietary switching technique to reduce glitch energy and maximize dynamic accuracy. Differential current outputs support single-ended or differential applications. The differential outputs each provide a nominal full-scale current from 2 mA to 20 mA.

The AD9751 is manufactured on an advanced low cost 0.35 µm CMOS process. It operates from a single supply of 3.0 V to 3.6 V and consumes 155 mW of power.

PRODUCT HIGHLIGHTS

The AD9751 is a member of a pin compatible family of high speed TxDAC+s, providing 10-, 12-, and 14-bit resolution.
Ultrahigh Speed 300 MSPS Conversion Rate.
Dual 10-Bit Latched, Multiplexed Input Ports. The AD9751 features a flexible digital interface allowing high speed data conversion through either a single or dual port input.
Low Power. Complete CMOS DAC function operates on 155 mW from a 3.0 V to 3.6 V single supply. The DAC full-scale current can be reduced for lower power operation.
On-Chip Voltage Reference. The AD9751 includes a 1.20 V temperature compensated band gap voltage reference.
