... VRB = +2V and 1.5V p-p analog input range, depending on your selection of amplifiers which may provide less than +4V output. 5. The ADC-318 and ADC-318A have resistor matrix taps at VRM1 (pin 4), VRM2 (pin 7) and VRM3 (pin 9). These pins provide ¼, ½ and ¾ full scale of VRT-VRB voltage respec- tively ...

... ADC-318, ADC-318A APPLICATION This device can be used in applications where 3 parallel channels are synchronized. Conversion speed is the highest in the de-multiplexed mode difficult to control timing of three channels at such a high speed. Two practical ways to maintain timing for reading data into the system are given. ...
