DS1848B-010+

The DS1848B-010+ is a dual temperature-controlled NV variable resistor and memory in 16 pin CSBGA package. DS1848-010 consists of two 10Kohm 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. 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 13bit, 2's complement value over the serial bus. The interface I/O pins consist of SDA and SCL.

• Supply voltage range from 3V to 5.5V
• Two 10Kohm with 256 position
• Resistor current is 3mA, supply current is 0.5mA
• Programming temperature range from 0°C to +70°C
• 128bytes of user EEPROM
