The AD7249BNZ is a dual 12-bit voltage-output digital-to-analog converter from Analog Devices, part of the DACPORT® series. It integrates two DACs with output amplifiers and a Zener voltage reference on a single CMOS chip, requiring no external trims for full specified performance.
The device uses an R-2R architecture and provides buffered voltage outputs. Output voltage ranges are selectable via internal gain resistors: 0 V to +5 V, 0 V to +10 V with single supplies, or ±5 V with dual supplies. The serial interface (SPI) minimizes pin count and supports easy connection to microcontrollers and DSP processors. Data is clocked in as a 16-bit word, with channel select and 12-bit data.
Key electrical specifications include a settling time of 10 µs, a DAC update rate of 125 kHz, and integral nonlinearity of ±0.5 LSB (max) and differential nonlinearity of ±0.9 LSB (max). The analog supply voltage range is ±11.4V to 15.75V. The device operates over the industrial temperature range of -40°C to 85°C.
The AD7249BNZ is offered in a 16-lead PDIP package (16-DIP, 0.300" body width) with through-hole mounting. It supports both external and internal reference options, providing flexibility in system design.
