GENERAL DESCRIPTION

The AD7339 is a composite IC that contains both DAC and ADC functions. The device includes an 8-bit parallel A-to-D converter. Two 8-bit parallel DACs are also included as are two serial control DACs. These serial DACs are 8-bit DACs.

The AD7339, which operates with a single 5 V power supply, has a bandgap reference on board with a nominal value of 2.5 V. To reduce the power consumption of the part, each section, except the reference, can be individually powered down when not in use.

The AD7339 is available in a 52-lead PQFP package.
