The DAC7578SPW is a 12-bit voltage output Digital-to-analogue Converter provides good linearity and minimizes undesired code-to-code transient voltages (glitch). The devices use 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 DAC incorporate a power-on-reset (POR) circuit that ensures the DAC output powers up to zero-scale or midscale until a valid code is written to the device. This device also contains a power-down feature, accessed through the serial interface, that reduces the current consumption of the devices to typically 0.42μA at 5V. Power consumption is typically 2.32mW at 3V, reducing to 0.68μW in power-down mode. The low power consumption and small footprint make these devices ideal.
