GENERAL DESCRIPTION

The AD9712B and AD9713B D/A converters are replacements

for the AD9712 and AD9713 units which offer improved ac and

dc performance. 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 ECL-

compatible device featuring update rates of 100 MSPS mini-

mum; the TTL-compatible AD9713B will update at 80 MSPS

minimum.

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 to +85°C. Both are also available for extended tempera-

ture ranges of –55

°C to +125°C in cerdips and 28-pin LCC

packages.
