AD9721

a 10-Bit, 400 MSPS D/A Converters AD9720/AD9721 FEATURES lated bipolar process. The AD9720 is ECL compatible, and will 400 MSPS (ECL)/100 MSPS (TTL) Update Rate update up to 400 MSPS; the AD9721 is TTL compatible and Low Glitch Impulse: 1.5 pV-s will update up to 100 MSPS. Fast Settling: 4.5 ns to 1/2 LSB Low Power: 1.1 W On-Board Quadrature Logic for DDS Applications Differential Clock (ECL) Designed for direct digital synthesis (DDS), waveform reconstruction, 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. APPLICATIONS Direct Digital Synthesis Arbitrary Waveform Synthesis Waveform Reconstruction High Speed Imaging OGENERAL DESCRIPTION BThe AD9720 and AD9721 D/A converters are 10-bit, high speed digital-to-analog converters constructed in an oxide iso- Both converters are characterized for dynamic performance, and have excellent harmonic suppression and spectral purity in waveform gen...
