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

The DAC8565 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 DAC8565 use a versatile 3-wire serial Interface that operates at Clock rates up to 50MHz. It is compatible with standard SPI?, QSPI?, Microwire?, and digital signal processor (DSP) Interfaces
The DAC8565 incorporates a power-on-reset circuit that ensures the DAC output powers up at either zero-scale or mid-scale 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 DAC8565 is drop-in and functionally compatible with the DAC8555 and pin-compatible with the DAC8534 DAC8554 and DAC8564. The DAC8565 is available in a TSSOP-16 package.
