DESCRIPTION
The DS1848 Dual Temperature-Controlled Nonvolatile (NV) Variable Resistor consists of two 256-
position linear, variable resistors. The DS1848-050 consists of one 10k
DS1848-010 consists of two 10k
resistors; both incorporate a direct-to-digital temperature sensor. The
device provides an ideal method for setting and temperature-compensating bias voltages and currents in
control applications using a minimum of circuitry.
and one 50k
while the
The variable resistors settings are stored in EEPROM memory and can be accessed over the industry
standard 2-wire serial bus. The value of each variable resistor is determined by a temperature-addressed
look-up table, which can assign a unique value to each resistor for every 2°C increment over the -40°C to
+95°C range. The output of the digital temperature sensor is also available as a 13-bit, 2’s complement
value over the serial bus. The interface I/O pins consist of SDA and SCL.
