Both of the DACs can be programmed with any temperature coefficient, which means that any system temperature effects can be corrected without any additional external devices. The DS1851 provides an ideal method for setting and temperaturecompensating bias voltages and currents in control applications using a minimal amount of external circuitry. The user-defined settings for both DACs are stored in two EEPROM look-up tables...
