SPT9713

SPT9713 12-BIT, 100 MWPS TTL D/A CONVERTER TECHNICAL DATA FEBRUARY 15, 2001 FEATURES 12-Bit, 100 MWPS digital-to-analog converter TTL compatibility Low power: 640 mW 1/2 LSB DNL 40 MHz multiplying bandwidth Industrial temperature range Superior performance over AD9713 – Improved settling time of 13 ns – Improved glitch energy 15 pV-s – Master-slave latches APPLICATIONS Fast frequency hopping spread spectrum radios Direct sequence spread spectrum radios Microwave and satellite modems Test & measurement instrumentation GENERAL DESCRIPTION The SPT9713 is a 12-bit, 100 MWPS digital-to-analog converter designed for direct digital synthesis, high resolution imaging, and arbitrary waveform generation applications. This device is pin-for-pin compatible with the AD9713 with significantly improved performance. The only difference between the SPT9713 and the AD9713 is that the Latch Enable (LE, pin 26) for the SPT9713 is rising-edge triggered (see figure 1), whereas the Latch Enable (LE, pin 26) for the AD9713 functions in the transparent mode. The SPT9713 is a TTL-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 SPT9713 is available in a 28-lead PLCC package in the industrial temperature range (–40 to +85 °C).
