Product details

The AD8802/AD8804 are 12-channel potentiometer divider TrimDACs®Digital-to-analog convertersA separate digitally controlled voltage output is available in a compact 20-pin package. It replaces the mechanical regulator function in new designs and is ideal for DC voltage regulation applications.

The AD8802 has a midscale preset function that can be easily programmed through the serial interface microcontroller port, making it ideal for replacing potentiometers that adjust from nominal values. These devices are ideal for many applications, such as gain control in video amplifiers, voltage control frequency and bandwidth in video equipment, geometry correction and auto-tuning in CRT computer graphics displays, and more. The AD8804 can independently control the top and low sides of the potentiometer divider, allowing V to be passedREFLThe pin determines the zero-scale voltage setting individually. This feature helps maximize resolution for devices with a limited allowable voltage control range.

The AD8802/AD8804 contain 12 voltage output digital-to-analog converters (DACs) that share a reference input.

Each DAC maintains its output state with its own DAC latches, which are updated by an internal serial-to-parallel shift register that loads data from a standard 3-wire serial input digital interface. The serial data input word is decoded, and the first four bits determine the DAC latch address where the last 8 bits of data need to be loaded. Operating from a 5 V supply, the AD8802/AD8804 consume only 10 μA. In addition, in shutdown mode, the reference input power consumption is reduced to 10 μA, leaving only the DAC latch setting for use when normal operation is returned.

The AD8802/AD8804 are available in three packages: 20-lead plastic DIP, SOIC-20 surface mount, and 1 mm low profile TSSOP-20 package.
