Overview
The AD5627RBRMZ-1, produced by Analog Devices Inc., is a member of the nanoDAC family, specifically a dual, 12-bit buffered voltage-out digital-to-analog converter (DAC). This device operates from a single 2.7 V to 5.5 V power supply and is guaranteed monotonic by design. It features an I2C-compatible serial interface that supports standard (100 kHz), fast (400 kHz), and high speed (3.4 MHz) modes. The AD5627RBRMZ-1 includes an on-chip reference and is designed for low power consumption, making it suitable for portable battery-operated equipment.
