TQ6124
1 Gigasample/sec,
14-bit
Digital-to-Analog
Convertor
The TQ6124 is a 14-bit monolithic digital-to-analog converter. The TQ6124
achieves conversion accuracy by using a segmented architecture, precision
current sources, and on-chip nichrome resistors. The only external
components required are an external reference and loop control amplifier.
The TQ6124 is ideally suited for applications in direct digital synthesis,
pixel generation for high-resolution monitors, broadband video generation,
and high-speed arbitrary waveform generators.
