the ADS-917 dissipates 1.9W (1.6W for ±12V)

maximum. The unit is offered with a unipolar

input (0 to +10V). Models are available for use in

either commercial (0 to +70°C) or HI-REL (–55 to

+125°C) operating temperature ranges. Applica-

tions include radar, sonar, spectrum analysis, and

graphic/medical imaging.
