16-Bit, Quad Channel, Ultra-Low Glitch, Voltage Output DAC With 2.5V, 2ppm/°C Internal Reference

The DAC8564 is a low-power, voltage-output, four-channel, 16-bit digital-to-analog converter (DAC). The device includes a 2.5V, 2ppm/C internal reference (enabled by default), giving a full-scale output voltage range of 2.5V. The internal reference has an initial accuracy of 0.02% and CAN source up to 20mA at the VREFH/VREFOUT pin. The device is monotonic, provides very good linearity, and minimizes undesired code-to-code transient voltages (glitch). The DAC8564 uses a versatile 3-wire serial Interface that operates at Clock rates up to 50MHz. The Interface is compatible with standard SPI?, QSPI?, Microwire?, and digital signal processor (DSP) Interfaces
The DAC8564 incorporates a power-on-reset circuit that ensures the DAC output powers up at zero-scale and remains there until a valid code is written to the device. The device contains a power-down feature, accessed over the serial Interface that reduces the current consumption of the device to 1.3A at 5V. The low-power consumption, internal reference, and small footprint make this device ideal for portable, battery-operated equipment. The power consumption is 2.9mW at 3V, reducing to 1.5W in power-down mode.
The DAC8564 is drop-in and functionally compatible with the DAC8534 and DAC8554 and pin-compatible with DAC8555 and DAC8565. The DAC8564 is available in a TSSOP-16 package.
