产品概述

The MAX5488EUD+ from Maxim Integrated Products is a dual, non-volatile, SPI interface, linear taper digital potentiometer in 14 pin TSSOP package. This digital potentiometers function as mechanical potentiometer with a simple 3-wire SPI compatible digital interface that programs the wipers to any one of 256 tap positions. Wiper position stored in non-volatile memory (EEPROM) and recalled upon power-up or recalled by an interface command. It features a non volatile memory (EEPROM) to return the wipers to their previously stored positions upon power-up. The MAX5488 has end to end resistance of 50Kohm. This device has a low 35ppm/°C end to end temperature coefficient and operates from a single +2.7V to +5.25V supply. Typical applications include LCD screen adjustment, audio volume control, mechanical potentiometer replacement, low drift programmable filters and low drift programmable gain amplifiers.
  • Supply voltage range from 2.7V to 5.25V (single supply operation), supply current of 400µA
  • Operating temperature range from -40°C to 85°C
  • 5ppm/°C ratiometric temperature coefficient (voltage divider mode), 0.75µs wiper settling time
  • Reliability of 200,000 wiper store cycles
  • Reliability of 50 years wiper data retention
  • ±0.5LSB DNL in voltage divider mode, 90KHz -3dB bandwidth, -90dB crosstalk
  • ±1 LSB INL (integral nonlinearity) in voltage divider mode
  • Full scale error of -0.6LSB, zero scale error of -0.6LSB (voltage divider mode)
  • Audio Volume Control; LCD Screen Adjustment; Low-Drift Programmable Filters; Low-Drift Programmable-Gain Amplifiers; Mechanical Potentiometer Replacement
