产品概述

The DS1855E-010+ is a dual, non-volatile digital potentiometer and secure memory in 14 pin TSSOP package. This device consists of one 100 position linear taper potentiometer, one 256 position linear taper potentiometer. It features a new software write protect which is an upgrade of DS1845. The DS1855 provides an ideal method for setting bias voltages and currents in control applications using a minimum of circuitry. The EEPROM memory allows user to store configuration or calibration data for a specific system or device and provides control of potentiometer wiper settings. Any type of user information may reside in the first 248 bytes of this memory. The next two addresses of EEPROM memory are for potentiometer settings and the remaining 6 bytes of memory are reserved.
  • Supply voltage range is 2.7V to 5.5V
  • Operating temperature range from -40°C to 85°C
  • 256 bytes of EEPROM memory
  • Access to data and potentiometer control via 2-wire interface
  • External write-protect pin to protect data and potentiometer settings
  • Data and potentiometer settings can be write protected through software control
  • End to end resistance is 10Kohm at ±20% tolerance and temperature coefficient is 750ppm/°C

应用

信号处理, 音频, 便携式器材, 消费电子产品, 工业, 系统监控
