TQ6124 1 Gigasample/sec/ 14-bit Digital-to-Analog Convertor

The TQ6124 registers incoming bits in a master latch array. The value of the four most-significant bits is encoded into an n-of-15 thermometer code while the ten low-order bits pass though an equalizing delay stage. All 25 bits are re-registered in a 25-wide slave latch array which drives a set of 2.

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, a.
