The DAC8564 is a low-power, voltage-output, four-channel, 16-bit digital-to-analog converter.
It includes a 2.5-V, 2-ppm/°C internal reference and features a full-scale 2.5-V output voltage range. The internal reference has an initial accuracy of 0.004% and can source up to 20 mA at the VREFH/VREFOUT pin.
The DAC8564 is monotonic, provides very good linearity, and minimizes undesired code-to-code transient voltages, also known as glitch. It uses a three-wire serial interface, operating at clock rates up to 50 MHz and compatible with standard SPI, QSPI, Microwire, and digital signal processor interfaces. The DAC8564 incorporates a power-on-reset circuit, ensuring the DAC outputs power-up at zero-scale and remains there until a valid code is written to the device. A power-down feature is included to reduce the current consumption of the device to 1.3 µA at 5 V. Power consumption is 2.9 mW at 3 V, reducing to 1.5 µW in power-down mode.
The DAC8564 is ideal for portable, battery-operated equipment, as well as closed-loop servo-control, process control, PLCs, data acquisition systems, programmable attenuation, and PC peripherals. It is has a relative accuracy of 4 LSB and a temperature range of –40° to +105°C.
