GENERAL DESCRIPTION
The AD5660 parts are a member of the nanoDAC family of devices. They are low power, single, 16-bit buffered voltage-out DACs, guaranteed monotonic by design. The AD5660x-1 operate from a 3 V single supply featuring an internal reference of 1.25 V and an internal gain of 2. The AD5660x-2/3 operate from a 5 V single supply featuring an internal reference of 2.5 V and an internal gain of 2. Each reference has a 10 ppm/°C max temperature coefficient. The reference associated with each part is available at the REFOUT pin. The part incorporates a power-on reset circuit that ensures that the DAC output powers up to 0 V (AD5660x-1/2) or midscale (AD5660x-3) and remains there until a valid write takes place. The part contains a power-down feature that reduces the current consumption of the device to 200 nA at 5 V and provides software selectable output loads while in power-down mode. The AD5660 uses a versatile three-wire serial interface that operates at clock rates up to 30 MHz and is compatible with standard SPITM, QSPITM, MICROWIRETM and DSP interface
standards. Its on-chip precision output amplifier allows rail-torail output swing to be achieved. The low power consumption of this part in normal operation makes it ideally suited to portable battery operated equipment. The power consumption is 0.7 mW at 5 V reducing to 1 µW in power-down mode. The AD5660 is designed with new technology and is the next generation to the AD53xx family.
