GENERAL DESCRIPTION
2.5V REFERENCE AVDD
The AD7339 is a posite 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,...
