the ADS-916 dissipates 1.8W (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.

... Invalid Data = 500kHz The ADS-916 is an edge-triggered device. All internal operations are triggered by the rising edge of the start convert pulse, which may be as narrow as 50nsec. All production testing is performed at a 500kHz sampling rate with 200nsec wide start pulses. For lower sampling rates, wider start pulses may be used, however, a minimum pulse width low of 50nsec must be maintained ...
