The AD5624/AD5664, members of the nanoDAC® family, are low power, quad, 12-, 16-bit buffered voltage-out DACs that operate from a single 2.7 V to 5.5 V supply and are guaranteed monotonic by design.
The AD5624/AD5664 require an external reference voltage to set the output range of the DAC. The part incorporates a power-on reset circuit that ensures the DAC output powers up to 0 V and remains there until a valid write takes place. The parts contain a power-down feature that reduces the current consumption of the device to 480 nA at 5 V and provides software-selectable output loads while in power-down mode.
The low power consumption of these parts in normal operation makes them ideally suited to portable battery-operated equipment. The power consumption is 2.25 mW at 5 V, going down to 2.4 μW in power-down mode.
The AD5624/AD5664 on-chip precision output amplifier allows rail-to-rail output swing to be achieved.
The AD5624/AD5664 use a versatile 3-wire serial interface that operates at clock rates up to 50 MHz, and are compatible with standard SPI®, QSPI™, MICROWIRE™, and DSP interface standards.

At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
The EVAL-AD5664REBZ (Cypress based) is no longer available. Please use EVAL-AD5664RDBZ (SDP based).
The EVAL-AD5664RDBZ evaluation board helps users quickly prototype new AD5664R circuits and reduce design time. The AD5664R operates from a single 2.7 V to 5.5 V supply.
For full data, see the AD5664R data sheet, which must be used in conjunction with user guide UG-986 when using the EVALAD5664RDBZ evaluation board.
The EVAL-AD5664RDBZ evaluation board interfaces to the USB port of a PC via the SDP-B controller board. Software that allows users to program the AD5664R can be downloaded via the EVAL-AD5664RDBZ product page.
The EVAL-AD5664RDBZ evaluation board requires the EVALSDP-CB1Z board (SDP-B controller board).
