DS1856B+ - Brand New Maxim Integrated Digital Potentiometers
-
Description
The DS1856B+ is a dual, temperature-controlled, nonvolatile (NV) variable resistor with three monitors. It consists of two 256-position, linear, variable resistors, three analog monitor inputs (MON1, MON2, MON3), and a direct-to-digital temperature sensor. This electronic component is designed to provide an ideal method for setting and temperature-compensating bias voltages and currents in control applications with minimal circuitry. The variable resistor settings are stored in EEPROM memory and can be accessed over the 2-wire serial bus.
Specifications and features
- SFF-8472 Compatible
- Five Monitored Channels: Temperature, VCC, MON1, MON2, MON3
- Three External Analog Inputs (MON1, MON2, MON3) That Support Internal and External Calibration
- Scalable Dynamic Range for External Analog Inputs
- Internal Direct-to-Digital Temperature Sensor
- Alarm and Warning Flags for All Monitored Channels
- Two Linear, 256-Position, Nonvolatile Temperature Controlled Variable Resistors
- Resistor Settings Changeable Every 2°C
- Three Levels of Security
- Access to Monitoring and ID Information Configurable with Separate Device Addresses
- 2-Wire Serial Interface
- Two Buffers with TTL/CMOS-Compatible Inputs and Open-Drain Outputs
- Operates from a 3.3V or 5V Supply
- -40°C to +95°C Operating Temperature Range
Application Scenarios
The DS1856B+ can be used in various applications, including control systems that require temperature-compensating bias voltages and currents. It is suitable for both 3.3V and 5V supply systems and can operate in the temperature range of -40°C to +95°C. This electronic component provides precise and reliable variable resistor settings, making it an ideal choice for applications that require accurate temperature compensation.
Comparison
The DS1856B+ offers several advantages, such as compatibility with SFF-8472, five monitored channels for temperature and other parameters, and internal direct-to-digital temperature sensing. It also has alarm and warning flags for all monitored channels and three levels of security. However, it is important to note that the resistor settings can only be changed every 2°C, which may limit its flexibility in certain applications.
