The MAX5841MEUB+ is a quad, 10bit, 2-wire, serial voltage-output digital to analogue converter (DAC) in 10 pin µMAX package. The DAC with an I2C compatible, 2-wire interface that operates at clock rates up to 400KHz. This low power device operates from a single supply and draws only 230µA at VDD = 3.6V, a power down mode decreases current consumption to less than 1µA. It has a double buffered I2C compatible serial interface that allows multiple devices to share a single bus. All logic inputs are CMOS logic compatible and buffered with schmitt triggers allowing direct interfacing to optocoupler and transformer isolated interfaces. The device minimizes digital noise feed-through by disconnecting the clock (SCL) signal from the rest of the device when an address mismatch is detected. It is used in digital gain and offset adjustments, programmable voltage and current sources, programmable attenuation, VCO/varactor diode control, low cost instrumentation and ATE.
