The AD5662 is a low cost and low power single 16-bit buffered voltage-out guaranteed monotonic DAC.
The part incorporates a power-on-reset circuit that depending on model ensures that the DAC output powers up to zero volts or midscale and remains there until a valid write takes place. Power consumption is typically 250 µA and the part contains a power-down feature that reduces the current consumption of the device to 1 µA at 5 V with software selectable output loads while in power-down mode.
The AD5662 utilizes a versatile three-wire serial interface that operates at clock rates up to 30 MHz and is compatible with standard SPI™, QSPI™, MICROWIRE™ and DSP interface standards. Its on-chip precision output amplifier allows rail-to rail output swing to be achieved.
