The AD7945BR is a 12-bit multiplying digital-to-analog converter (DAC) from Analog Devices, part of the AD7943/AD7945/AD7948 family. It uses an R-2R architecture with current output unbuffered and requires an external reference. The device operates from a single 5V supply and features a parallel data interface with 40 ns write pulsewidth. Key specifications include a typical settling time of 600 µs, ±0.5 LSB maximum integral nonlinearity (INL) and differential nonlinearity (DNL), and output leakage current of 10 nA maximum. The DAC offers a gain error of ±2 LSB over temperature and a gain temperature coefficient of 2 ppm FSR/°C. The operating temperature range is -40°C to 85°C. The AD7945BR is available in a 20-lead SOIC (20-SOIC, 7.50mm width) surface mount package. Typical applications include battery-powered instrumentation, laptop computers, and upgrades for 754x series DACs. The device features low power consumption of 5 mW typical and low glitch of 60 nV-s with an amplifier connected.
