... A/D converter, a precise voltage reference, timing/control logic, and error- correction circuitry. Digital input and output levels are TTL. Requiring ±15V (or ±12V) and +5V supplies, the ADS-926 dissipates only 1.75W (1.6W for ±12V), maximum. The unit is offered with a bipolar input (–5V to +5V). Models are available for use in either commercial (0 to +70° ...

... For the ADS-926, offset adjusting is normally accomplished at the point where the MSB and all other output bits are 0's and the LSB just changes from This digital output transition ideally occurs when the applied analog input is +½ ...

... Invalid Data = 500kHz The ADS-926 is a pulse-triggered device. Its internal operations are triggered by both the rising and falling edges of the start convert pulse. When sampling at 500kHz, the start pulse must be between 175 and 225nsec wide. For lower sampling rates, wider start pulses may be used, however, a 50nsec minimum pulse width low must be maintained ...
