DAC7678 Digital to Analog Converters

The Texas Instruments DAC7678 digital-to-analog converter (DAC) is a low-power, voltage-output, octal channel, 12-bit data converter. The TI 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 V_REFIN/V_REFOUT pin. The TI DAC7678 DAC is monotonic, provides very good linearity, and minimizes undesired code-to-code transient voltages (glitch). The TI 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 TI 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.
