DAC8564IAPW .

The DAC8564IAPW is a low-power voltage-output 4-channel 16-bit Digital-to-analog Converter (DAC) includes a 2.5V, 2ppm/°C internal reference, giving a full-scale output voltage range of 2.5V. The internal reference has an initial accuracy of 0.004% 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. 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 1.3µA at 5V. Power consumption is 2.9mW at 3V, reducing to 1.5µW in power-down mode.
