Product Overview

MAX5418 is a 256-tap, non-volatile, I²C-interface, digital potentiometer performs the function of a mechanical potentiometer by replacing the mechanics with a simple 2-wire digital interface, allowing communication with multiple devices. This device performs the same function as a discrete potentiometer or variable resistor and has 256 tap points. The devices feature an internal, non-volatile EEPROM used to store the wiper position for initialization during power-up. The fast-mode I²C-compatible serial interface allows communication at data rates up to 400kbps, minimizing board space and reducing interconnection complexity in many applications. This makes the devices ideal for applications requiring a low-temperature-coefficient variable resistor, such as low-drift, programmable gain amplifier circuit configurations. Applications include mechanical potentiometer replacement, low-drift programmable-gain amplifiers, volume control, liquid-crystal display (LCD) contrast control.
  • Power-on recall of wiper position from non-volatile memory
  • 100kohm typical end-to-end resistance (VDD = +2.7V to +5.25V, TA = +25°C)
  • 500nA (typ) static supply current, +2.7V to +5.25V single-supply operation range
  • 256taps minimum resolution (VDD = +2.7V to +5.25V, TA = +25°C)
  • Integral nonlinearity is ±0.5LSB (maximum, VDD = +2.7V to +5.25V, TA = +25°C)
  • Full-scale error is -0.3LSB (typ, 100kohm, VDD = +2.7V to +5.25V, TA = +25°C)
  • 50KHz wiper -3dB bandwidth (typ, VDD = +2.7V to +5.25V, TA = +25°C)
  • 2.70 to 5.25V power supply voltage range (VDD = +2.7V to +5.25V, TA = +25°C)
  • 8 lead TDFN-EP package, temperature range from -40°C to +85°C
