DESCRIPTION

The DS1851 dual temperature-controlled nonvolatile (NV) DACs consists of two DACs, two EEPROM look-up tables, and a direct-to-digital temperature sensor. 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 temperature compensating bias voltages and currents in control applications using a minimal amount of external circuitry.
