Overview
The AD5662ARMZ-1REEL7, produced by Analog Devices Inc., is a member of the nanoDAC family. It 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. This DAC is guaranteed monotonic by design and is particularly suited for applications requiring high precision and low power consumption. The AD5662 incorporates a power-on reset circuit and a power-down feature, reducing current consumption to 480 nA at 5 V, making it ideal for portable battery-operated equipment. The device features a versatile 3-wire serial interface compatible with standard SPI, QSPI, MICROWIRE, and DSP interface standards.
