Overview
The AD5660CRM-1REEL7, part of the nanoDAC™ family from Analog Devices Inc., is a low-power, single-channel, 16-bit digital-to-analog converter (DAC) with a buffered voltage output. This device is known for its high precision and low power consumption, making it suitable for a variety of applications. The AD5660 features an on-chip precision output amplifier that allows for rail-to-rail output swing and includes a power-on reset circuit that ensures the DAC output powers up to either 0 V or midscale, depending on the model variant. The device operates on a single 3 V or 5 V power supply and has a versatile 3-wire serial interface compatible with standard SPI®, QSPI™, MICROWIRE™, and DSP interface standards.
