AD5680BCPZ-2RL7

DAC 1CH Resistor-String 18Bit 8Pin LFCSP T/R

Product Details

The AD5680, a member of the _nano_DAC family, is a single, 18-bit buffered voltage-out digital-to-analog converter DAC 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 midscale 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.
