Texas Instruments DAC8564

The DAC8564 is a low-power, voltage-output, four-channel, 16-bit digital-to-analog converter (DAC). The DAC8564 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 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. It 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 DAC8564 contains a power-down feature, accessed over the serial interface, that reduces the current consumption of the device to 1.7A at 5V. The low-power consumption, internal reference, and small footprint make this device ideal for portable, battery-operated equipment. The power consumption is 3.1mW at 3V, reducing to 4.6W in power-down mode. The DAC8564 is pin-compatible with the DAC8534, DAC8554/55 and DAC8565. The DAC8564 is available in a TSSOP-16 package.
