What is an analog board? In the area of data acquisition products, an analog board is typically a board that provides an analog to digital (A/D) conversion function (input) or a board that provides a digital to analog (D/A) conversion function (output). Some data acquisition boards can have both A/D and D/A functions. These are sometimes referred to as system boards, or multi-application boards.

The range of A/D functions available on an analog input board can be from simple one- or two-channels with 12-bit resolution, to 64 channels with 16-bit resolution. Other A/D analog input board configurations can include Digital I/O.

The A/D conversion rate of analog input boards can range from a slow 50 Hz (one conversion every 20 milliseconds) to greater than 20 MHz (20 conversion every micro-second).

The range of D/A functions available on an analog output board can be from simple two- and four-channels with 12-bit resolution, to 32 channels with 16-bit resolution. Other D/A analog output board configurations can include digital I/O, and both analog voltage and/or current output capability.

An analog board, configured for either analog input or output can be selected for use with PCI, USB, PC/104, ISA, and PCMCIA buses.

Analog input and output functions are also available in a wide range of external signal conditioning modules and serial I/O modules.
