The DAC7564 is a low-power, voltage-output, four-channel, 12-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 DAC7564 uses a versaTIle 3-wire serial interface that operates at clock rates up to 50MHz. The interface iscompaTIble with standard SPI™, QSPI™, Microwire™, and digital signal processor (DSP) interfaces.
The DAC7564 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.
