... Data Sheet 8-Bit, 125/60MSPS, Dual High Speed CMOS D/A Converter The HI5628 is an 8-bit, dual 125MSPS D/A converter which is implemented in an advanced CMOS process. Operating from a single +5V to +3V supply, the converter provides 20.48mA of full scale output current and includes an input data register. Low glitch energy and excellent frequency domain performance are achieved using a segmented architecture ...

... T The units are ppm per degree C. Detailed Description The HI5628 is a dual, 8-bit, current out, CMOS, digital to analog converter. Its maximum update rate is 125MSPS and can be powered by either single or dual power supplies in the recommended range of +3V to +5V. It consumes less than 330mW of power when using a +5V supply with the data switching at 100MSPS ...

... Digital Inputs and Termination The HI5628 digital inputs are guaranteed to CMOS levels. However, TTL compatibility can be achieved by lowering the supply voltage to 3V due to the digital threshold of the input buffer being approximately half of the supply voltage. The internal register is updated on the rising edge of the clock. To minimize reflections, proper termination should be implemented ...
