isolated bipolar process. T he AD9720 is ECL compatible, and
will update up to 400 MSPS; the AD9721 is T T L compatible
and will update up to 100 MSPS.
Designed for direct digital synthesis (DDS), waveform recon-
struction, and high resolution video applications, both devices
feature low glitch impulse of 1.5 pV-s and fast settling times of
4.5 ns to 1/2 LSB.
Both converters are characterized for dynamic performance, and
have excellent harmonic suppression and spectral purity in
waveform generation applications.
T he units are available in 28-lead DIPs, L CCs and SOICs.
