Product Summary
The AD7249BRZ is a 12-bit, voltage output, digital-to-analog converter with output amplifiers and Zener voltage reference on a monolithic CMOS chip. No external trims are required to achieve full specified performance. The AD7249BRZ is capable of developing +10 V across a 2 kΩ load. The output voltage ranges with single supply operation are 0 V to +5 V or 0 V to +10 V, while an additional bipolar ±5 V output range is available with dual supplies. The ranges are selected using the internal gain resistor. The applications of the AD7249BRZ include Process Control, Industrial Automation, Digital Signal Processing Systems, Input/Output Ports.
