AD8801AR

The AD8801AR is an octal 8-bit digital-to-analog converter (DAC) from Analog Devices / Maxim Integrated. It is part of the TrimDAC family, designed to replace mechanical trimmer potentiometers in digital control applications. The device provides eight individually programmable voltage outputs via a three-wire serial (SPI) interface.

Key specifications include 8-bit resolution with 8 DAC channels, typical settling time of 600 ns, and an R-2R ladder architecture. The output type is voltage - unbuffered, with an external reference. Integral nonlinearity (INL) is ±0.5 LSB maximum. The supply voltage range is 2.7 V to 5.5 V, and the operating temperature range is -40°C to +85°C.

The device is offered in a surface-mount 16-SOIC package (0.154", 3.90mm width) with a supplier device package of 16-SOIC. Mounting type is surface mount. The AD8801 includes a midscale preset and power shutdown feature that reduces consumption to ≤25 mW including I_DD and I_REF.

Typical applications include automatic adjustment circuits, trimmer potentiometer replacement, video and audio equipment gain and offset adjustment, and portable battery-operated equipment. The device is ideal for gain control of video amplifiers, voltage-controlled frequencies and bandwidths, geometric correction, and automatic adjustment in CRT computer graphic displays.
