The DAC7678 is a low-power, voltage-output, octal 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 has an initial accuracy of ±5mV 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, 2-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 up to either zero-scale or mid-scale until a valid code is written to the device. These devices contain a power-down feature, accessed over the serial interface that reduces the current consumption of the device to typically 0.42µA at 5V. Power consumption (including internal reference) is typically 3.56mW at 3V, reducing to 0.68µW in power-down mode. The low power consumption, internal reference, and small footprint make this device ideal for portable, battery-operated equipment. The DAC7678 is drop-in and functionally compatible with DAC5578, DAC6578, and DAC7578. All devices are available in a 4x4 QFN-24 package and a TSSOP-16 package.
