AD5676BRUZ

The AD5676BRUZ is a low power, octal, 16-bit buffered voltage output digital-to-analog converter (DAC) from Analog Devices. It provides high relative accuracy with a maximum integral nonlinearity (INL) of ±3 LSB at 16 bits and a total unadjusted error (TUE) of ±0.14% of full-scale range (FSR) maximum. Other key specifications include a maximum offset error of ±1.5 mV and a maximum gain error of ±0.06% of FSR. The device employs a string DAC architecture and offers a typical settling time of 8 µs.

The AD5676BRUZ operates from a single 2.7V to 5.5V power supply and is compatible with 1.8V logic. It supports an SPI interface with clock speeds up to 50 MHz, featuring readback and daisy chain capabilities. A user-selectable gain of 1 or 2 via the GAIN pin or gain bit allows flexible output scaling. The internal power-on reset circuit, combined with the RSTSEL pin, enables the outputs to power up to zero scale or midscale. Per-channel power-down mode reduces current consumption to typically 1 µA.

The DAC is available in a 20-lead TSSOP package (0.173", 4.40mm Width) for surface mount assembly. It operates over the extended industrial temperature range of -40°C to +125°C. Typical applications include optical transceivers, base station power amplifiers, process control (PLC I/O cards), industrial automation, and data acquisition systems.
