DS1845E-101 - Brand New Maxim Integrated IC Chips
-
Description
The DS1845E-101 is a dual NV potentiometer and memory in the IC chips category. It consists of one 100-position linear taper potentiometer, one 256-position linear taper potentiometer, 256 bytes of EEPROM memory, and a 2-wire interface. This device is designed to provide an easy method for setting bias voltages and currents in control applications with minimal circuitry. It also allows users to store configuration or calibration data for specific systems or devices, as well as control the potentiometer settings via the EEPROM memory.
Specifications and features
- Two linear taper potentiometers: DS1845-010 (10k, 100 position & 10k, 256 position), DS1845-050 (10k, 100 position & 50k, 256 position), DS1845-100 (10k, 100 position & 100k, 256 position)
- 256 bytes of EEPROM memory
- Access to data and potentiometer control via a 2-wire interface
- External Write Enable pin to protect data and potentiometer settings
- Nonvolatile wiper storage in 2 bytes of address space
- Operates from 3V or 5V supplies
- Packaging: Flip Chip Package, 16-ball STPBGA, 14-pin TSSOP
- Industrial operating temperature: -40ºC to +85ºC
- Programming temperature: 0ºC to +70ºCApplication Scenarios
The DS1845E-101 is widely used in control applications where there is a need to set bias voltages and currents. It is suitable for various devices and systems that require accurate configuration or calibration data storage. This model is commonly used in industrial settings due to its wide operating temperature range (-40ºC to +85ºC) and programming temperature range (0ºC to +70ºC).
