Product Details

The AD5663, a member of the nanoDAC® family, is a low power, dual, 16-bit buffered voltage-out DAC that operates from a single 2.7 V to 5.5 V supply and is guaranteed monotonic by design.

The AD5663 requires 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 or midscale (AD5663-1) 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 480 nA at 5 V and provides software-selectable output loads while in power-down mode.

The low power consumption of this part in normal operation makes it ideally suited to portable, battery-operated equipment. The power consumption is 1.25 mW at 5 V, going down to 2.4 μW in power-down mode.

The on-chip precision output amplifier of the AD5663 allows rail-to-rail output swing to be achieved.

The AD5663 uses a versatile, 3-wire serial interface that operates at clock rates up to 50 MHz and is compatible with standard SPI®, QSPI™, MICROWIRE™, and DSP interface standards.

EVAL-AD5663R Circuit Diagram

Product Details

The evaluation board is designed to allow straightforward customer evaluation of the device using the hardware and software provided. The evaluation board can also be used to quickly create a prototype with the AD5663R/AD5667R, reducing design time. The AD5663R/AD5667R operate from a single 2.7 V to 5.5 V supply. These are 16-bit, dual-channel, voltage output digital-to-analog converters (DACs). The AD5663R uses a serial peripheral interface (SPI) for configuration and control, whereas the AD5667R uses an I2C interface.

Full data on the AD5663R/AD5667R can be found in the appropriate data sheets available from Analog Devices and should be consulted in conjunction with the user guide UG-991 when using the evaluation board.

The evaluation board interfaces to the USB port of a PC via the SDP board.

This evaluation board requires the EVAL-SDP-CB1Z board (SDP-B controller board).
