Abstract
A data acquisition for use in a high-speed data bus interface is provided with an analog acquisition circuit having analog inputs, digital outputs, a load terminal, an end-of-conversion terminal, a strobe terminal, a multiplex address output and a channel select input. A static random access memory receives data produced at the digital output of the analog acquisition circuit and stores it in addresses corresponding to the multiplexed address outputs of the analog acquisition circuit. A simple logic control circuit having an AND gate, an OR gate and a one shot circuit is connected to control the operation of the analog acquisition to provide self-starting and free running operation with synchronous turn on and turn off to prevent data contamination when the circuit is stopped.
