The DAC7678 is a low-power, voltage-output, eight-channel, 12-bit digital-to-analog converter (DAC). The DAC7678 includes a 2.5V internal reference (disabled by default), giving a full-scale output voltage range of 5V. The internal reference iniTIal accuracy is ±1mV and can source up to 20mA at the VREFIN/VREFOUT pin. The device is monotonic, provides very good linearity, and minimizes undesired code-to-code transient voltages (glitch).
The DAC7678 uses a versaTIle, two-wire serial interface that is I2C-compaTIble and operates at clock rates of up to 3.4MHz. MulTIple devices can share the same bus.
The DAC7678 incorporates a power-on-reset circuit that ensures the DAC output powers on at either zero-scale or midscale until a valid code is written to the device.
