The AD5620/AD5640/AD5660 are 12-/14-/16-bit nanoDACs from Analog Devices with a 5 ppm/°C reference voltage. They are available in SOT-23 packages and have low power consumption. These products are suitable for applications such as process control, data acquisition systems, battery-powered instruments, digital gain and offset adjustment, programmable voltage and current sources, and programmable attenuators.
The AD5620/AD5640/AD5660 are members of the nanoDAC family, serving as low power, single buffered voltage-out DACs. They are guaranteed monotonic by design and available with 12-bit, 14-bit, or 16-bit resolution.
These devices feature an on-chip precision reference (1.25 V or 2.5 V) and operate from a single power supply of either 3 V or 5 V. They utilize a versatile 3-wire serial interface compatible with SPI, QSPI, MICROWIRE, and DSP standards.
