Overview
The MAX5434LEZT+T is a nonvolatile, linear-taper digital potentiometer featuring 32 tap points and a 50kΩ end-to-end resistance. It utilizes a fast-mode I²C-compatible serial interface for communication at data rates up to 400kbps. The device includes internal EEPROM that restores the wiper position upon power-up. It operates on a single supply voltage ranging from +2.7V to +5.25V with a typical static supply current of 500nA. The component is housed in a 6-pin thin SOT23 package and is specified over an extended temperature range of -40°C to +85°C.
Feature Summary
- Nonvolatile memory retains wiper position after power loss
- I²C-compatible serial interface supports 400kbps data rates
- 50kΩ nominal resistance with 35ppm/°C end-to-end temperature coefficient
- Compact 6-pin thin SOT23 package
Applications
- Mechanical potentiometer replacement
- Low-drift programmable-gain amplifier circuits
- Volume control systems
- Liquid-crystal display screen adjustment
Procurement Notes
Verify the ordering suffix 'T' indicates tape and reel packaging when sourcing components. Confirm the lead-free status denoted by the '+' suffix aligns with assembly requirements. Ensure the specific I²C address (0101000) matches the system bus configuration to avoid addressing conflicts with other devices on the same interface.
Selection Notes
Select this model for applications requiring a variable resistor configuration where the high terminal is internally connected to the wiper. Choose between 50kΩ (MAX5434) or 100kΩ (MAX5435) based on circuit impedance needs. The 6-pin SOT23 package is suitable for space-constrained designs compared to the 8-pin TDFN options available in the family.
Part Context
This component belongs to the MAX5432–MAX5435 series of 32-tap, nonvolatile, I²C, linear digital potentiometers. The MAX5434 variant specifically provides 50kΩ resistance in a 6-pin thin SOT23 package. Other variants in the series include different resistance values and package types, such as the 8-pin TDFN packages used by the MAX5432 and MAX5433 models.
Replacement Considerations
The MAX5434MEZT+T and MAX5434NEZT+T are confirmed substitutes within the same package and resistance class, differing only in factory-programmed I²C addresses.
