the ADS-919 typically dissipates 1.8W (1.5W for
±12V). The unit is offered with a unipolar input (0
to +10V). There are four models of the ADS-919
covering three operating temperature ranges, 0
to +70°C, -40 to +85°C, –55 to +125°C and one
high reliability “883” model is also available. All
models are housed in the same ceramic package.
Each model is available in Non-RoHS version or
RoHS compliant (-C) version. Applications include
radar, sonar, spectrum analysis, and graphic/
medical imaging.

... The ADS-919 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 20nsec. All production testing is performed at a 2MHz sampling rate with 200nsec wide start pulses. For lower sampling rates, wider start pulses may be used, however, a minimum pulse width low of 20nsec must be maintained ...
