... 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-929 typically dissipates 1.7W (1.4W for ±12V). 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-929, 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 ...

... Data N Valid 425ns min. = 2MHz The ADS-929 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 ...
