Like their predecessors, they are 12-bit, high speed digital-to-analog converters fabricated in an advanced oxide isolated bipolar process. The AD9712B is an ECLcompatible device featuring update rates of 100 MSPS minimum; the TTL-compatible AD9713B will update at 80 MSPS minimum. – CONTROL AMP OUT 20 REFERENCE OUT 19 CONTROL AMP IN Designed for direct digital synthesis, waveform reconstruction, and high resolution imaging applications, both devices feature low glitch impulse of 28 pV-s and fast settling times of 27 ns. Both units are characterized for dynamic performance and have excellent harmonic suppression. The AD9712B and AD9713B are available in 28-pin plastic DIPs and PLCCs, with an operating temperature range of –25°C ...
