The SPT9713 is a 12-bit, 100 MWPS digital-to-analog converter designed for direct digital synthesis,high reso-lution imaging,and arbitrary waveform generation applica-tions.

This device is pin-for-pin compatible with the AD9713 withsignificantly improved performance. The only differencebetween the SPT9713 and the AD9713 is that the LatchEnable (LE, pin 26) for the SPT9713 is rising-edge trig-gered (see figure 1), whereas the Latch Enable (LE, pin26) for the AD9713 functions in the transparent mode.

The SPT9713 is a TTL-compatible device. It features afast settling time of 13 ns and low glitch impulse energy of15 pV-s, which results in excellent spurious-free dynamicrange characteristics.

The SPT9713 is available in a 28-lead PLCC package in the industrial temperature range (40 to +85 °C).
