GENERAL DESCRIPTION
The SPT9712 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 AD9712 with
significantly improved performance. The only difference
between the SPT9712 and the AD9712 is that the Latch
Enable (LE, pin 26) for the SPT9712 is rising-edge trig-
gered (see figure 1), whereas the Latch Enable (LE, pin
26) for the AD9712 functions in the transparent mode.
The SPT9712 is an ECL-compatible device. It features a
fast settling time of 13 ns and low glitch impulse energy of
15 pV-s, which results in excellent spurious-free dynamic
range characteristics.
The SPT9712 is available in a 28-lead PLCC package in
the industrial temperature range (–40 to +85 °C).
