Overview
The AD5624RBCPZ-3REEL7, produced by Analog Devices Inc., is a member of the nanoDAC® family. This component is a low-power, quad, 12-bit buffered voltage-out digital-to-analog converter (DAC). It operates from a single 2.7 V to 5.5 V supply and is guaranteed monotonic by design. The device features an on-chip reference with options for 1.25 V or 2.5 V, each with a temperature coefficient of 5 ppm/°C. The AD5624R is particularly suited for applications requiring low power consumption, making it ideal for portable battery-operated equipment.
