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.  
The user-defined settings for both DACs are stored in two EEPROM look-up tables and can be accessed  
over the industry-standard 2-wire serial bus, which consists of SDA and SCL pins. These look-up tables  
can assign a unique output value to each DAC for every 4°C increment over the -40°C to +95°C range.  
The output of the digital temperature sensor is also available as a 12-bit, two’s complement value over the  
serial bus.
