Overview
- Two temperature-controlled 8-bit Digital-to-Analog Converters (DACs)
- DAC settings changeable every 4°C
- Access to temperature data and device control through a 2-wire interface
- Operates with +3.3V or +5V supplies
- Packaging: 8-pin TSSOP
- Operating temperature: -40°C to +95°C
- Programming temperature: 0°C to +70°C
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.
