TQ6124

T R I Q U I N T S E M I C O N D U C T O R, I N C . 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.
