We describe a simple and inexpensive circuit for analog data acquisition with high speed and high resolution, for use in an IBM PC-AT or compatible. The circuit is suitable for a wide range of applications in electrophysiology. Features of the circuit include multichannel reading, programmable sampling rate, and direct memory access controlled dual buffering for continuous recording. A program written in the C programming language for control of data acquisition is also given.
