The ranges of adjustment for the circuits in Figures ers between 1 and 0. 2 and 3 are guaranteed to compensate for the ADS-947’s initial accuracy errors and may not be able to compensate for additional system errors. 3. To confi rm proper operation of the device, vary the input signal to obtain the output coding listed in Table 2. A/D converters are calibrated by positioning their digital outputs exactly on the transition point between two adjacent digital output codes. This can be accomplished by connecting LED’s to the digital outputs and adjusting until certain LED’s “fl icker” equally between on and off. Other approaches INPUT VOLTAGE ZERO ADJUST GAIN ADJUST RANGE +½ LSB +FS –1½ LSB employ digital comparators or microcontrollers to detect when the outputs change from one code to the next. ±2V +122μV +1.99963V Offset adjusting for the ADS-947 is normally accomplished at the point Table 1.

Scale is approximately 5ns per division. Sampling rate = 10MHz. 2. The start convert pulse must be between 20 and 50ns wide or between 80 and 100ns wide (when sampling at 10MHz) to ensure proper operation. For sampling rates less than 10MHz, the start pulse can be wider than 85nsec, however a minimum pulse width low of 15nsec should be maintained. A 10MHz clock with a 20nsec positive pulse width is used for all production testing. 3. For no latency delay and an input range of ±0.5 Volts, order ADS-947MC-31122. Figure 4.
