The DS1848 Dual Temperature-Controlled Nonvolatile (NV) Variable Resistor consists of two 256- position linear, variable resistors. The DS1848-050 consists of one 10kΩand one 50kΩ, while the DS1848-010 consists of two 10kΩ 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 13-bit, 2's complement value over the serial bus. The interface I/O pins consist of SDA and SCL. * Two linear taper, temperature-controlled variable resistors * DS1848-050 * One 50kΩ, 256 position * One 10kΩ, 256 position * DS1848-010 * Two 10kΩ, 256 position * Resistor settings changeable every 2°C * Access to temperature data and device control via a 2-wire interface * Operates from 3V or 5V supplies * Packaging: 14-pin TSSOP, 16-ball CSBGA * Operating temperature: -40°C to +95°C * Programming temperature: 0°C to +70°C * 128 bytes of user EEPROM https://elecena.pl/product/22301590/dual-temperature-controlled-nv-variable-resistor-memory 2022-12-25 https://elecena.pl/product/22301590/dual-temperature-controlled-nv-variable-resistor-memory 2025-01-19
