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.
