8-Bit, 125/60MSPS, High Speed D/A Converter

The HI5660 is an 8-bit, 125MSPS, high speed, low power, D/A converter which is implemented in an advanced CMOS process. Operating from a single +3V to +5V supply, the converter provides 20mA of full scale output current and includes edge-triggered CMOS input data latches. Low glitch energy and excellent frequency domain performance are achieved using a segmented current source architecture. For an equivalent performance dual version, see the HI5628.
