5 V 18-Bit nanoDAC® in a SOT-23

Manufactured by:

Product Details

The AD5680, a member of the nanoDAC® family, is a single, 18-bit buffered voltage-out digital-to-analog converter that operates from a single 4.5 V to 5.5 V supply and is 18-bit monotonic.

The AD5680 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 (AD5680-1) or to mid-scale (AD5680-2) and remains there until a valid write takes place.

The low power consumption of this part in normal operation makes it ideally suited to portable battery-operated equipment. The power consumption is 1.6 mW at 5 V.

The AD5680 on-chip precision output amplifier allows rail-to-rail output swing to be achieved. For remote sensing applications, the output amplifier’s inverting input is available to the user.

The AD5680 uses a versatile 3-wire serial interface that operates at clock rates up to 30 MHz, and is compatible with standard SPI®, QSPI™, MICROWIRE™, and DSP interface standards.

Product Details

The EVAL-AD5680EBZ (Cypress based) is no longer available. Please use EVAL-AD5680DBZ (SDP based).

The EVAL-AD5680DBZ evaluation board is designed to help users quickly prototype new AD5680 circuits and reduce design time. The AD5680 operates from a single 4.5 V to 5.5 V supply.

For full specifications, see the AD5680 data sheet, which must be used in conjunction with user guide UG-989 when using the evaluation board.

The EVAL-AD5680DBZ evaluation board interfaces to the USB port of a PC via the SDP-B board. Software is available for download via the EVAL-AD5680DBZ product page that allows users to program the AD5680.
