Description

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 0.004% 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 (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 1.3µA at 5V. Power consumption is 2.9mW at 3V, reducing to 1.5µW in power-down mode. The low-power consumption, internal reference, and small footprint make this device ideal for portable, battery-operated equipment.

The DAC8564 is drop-in and functionally compatible with the DAC7564 and DAC8164, and functionally compatible with the DAC7565, DAC8165, and DAC8565. All these devices are available in a TSSOP-16 package.
