Overview
The AD5662BRJ-1REEL7, produced by Analog Devices Inc., is a low-power, single 16-bit buffered voltage-out digital-to-analog converter (DAC) that operates from a single 2.7 V to 5.5 V supply. It is part of the nanoDAC family and is guaranteed monotonic by design. The device features a versatile 3-wire serial interface compatible with standard SPI®, QSPI™, MICROWIRE™, and DSP interface standards, operating at clock rates up to 30 MHz. The AD5662 includes a power-on reset circuit and multiple power-down functions, making it suitable for portable battery-operated equipment and applications requiring low power consumption.
