A circuit is described which provides fast acquisition of two analog signals by the Digital Equipment Corporation family of LSI 11, 11/2, and 11/23 microcomputers. This circuit digitizes each signal with 12 bits of resolution and stores the results directly in microcomputer memory via direct memory access. Real‐time data‐acquisition speeds up to three microseconds per pair of signals may be obtained.
