The AD7391AR is a 10-bit voltage output digital-to-analog converter (DAC) manufactured by Analog Devices. It is part of the AD7390/AD7391 family designed for single-supply 3V systems. The device operates from a supply voltage range of 2.7V to 5.5V and consumes less than 100 µA typical supply current, making it suitable for battery-operated applications.
The DAC uses an R-2R architecture and provides a buffered voltage output. The full-scale output voltage is determined by an external reference input, which can range from 0V to VDD. The device features a double-buffered serial data interface compatible with SPI and QSPI protocols, using SDI, CLK, and LD pins. A CLR input sets the output to zero scale on power-on or upon user demand.
Key electrical specifications include a typical settling time of 70 µs, integral nonlinearity (INL) of ±2 LSB maximum, and differential nonlinearity (DNL) of ±0.9 LSB maximum. The device is specified for operation over the industrial temperature range of -40°C to 125°C.
The AD7391AR is offered in an 8-lead SOIC surface-mount package (8-SOIC) with a width of 3.90mm. It is RoHS3 compliant and has an MSL rating of 1 (unlimited).
