An analog I/O board is a data acquisition board that provides both analog inputs (I) and analog outputs (O). The analog input is the input to analog-to-digital (A/D) converter, while the analog output is the output from a digital-to-analog (D/A) converter.

The range of A/D functions available on an analog I/O board can be from simple one or two channels with 12-bit resolution, to 16 channels with 16-bit resolution. The A/D conversion rate of an analog I/O Board can range from a slow 1 Hz (one conversion every second) to 20 MHz, or more.

The range of D/A functions available on an analog I/O board can be from simple two and four channel outputs with 12-bit resolution, to 32 channels with 16-bit resolution capability.

An analog I/O board often includes discrete digital bi-directional I/O lines, counter timers, and D/A converters for outputting analog signals for control applications.

An analog I/O board designed for high performance will work in a very wide range of test and measurement, and control applications. Combined with powerful software, a data acquisition board will turn a personal computer into a powerful measurement system that may be used to automate experiments, construct product test stands, monitor and control production equipment, or be embedded in products ranging from medical monitoring systems to automobile test simulators.
