DATASHEET HI5660 FN4521 Rev 7.00 8-Bit, 125/60MSPS, High Speed D/A Converter July 2004 The HI5660 is an 8-bit, 125MSPS, high speed, low power, Features D/A converter which is implemented in an advanced CMOS Throughput Rate 125MSPS process. Operating from a single +3V to +5V supply, the converter provides 20mA of full scale output current and Low Power . 165mW at 5V, 27mW at 3V includes edge-triggered CMOS input data latches. Low glitch Power Down Mode 23mW at 5V, 10mW at 3V energy and excellent frequency domain performance are Integral Linearity Error . 0.25 LSB achieved using a segmented current source architecture. For an equivalent performance dual version, see the HI5628. Adjustable Full Scale Output Current . 2mA to 20mA This device complements the HI5X60 family of high speed SFDR to Nyquist at 10MHz Output . 60dBc converters offered by Intersil, which includes 8, 10, 12, and Internal 1.2V Bandgap Voltage Reference 14-bit devices.
