Overview
The MAX5429EUA+ is a linear-taper digital potentiometer with an end-to-end resistance of 10 kΩ and 32 wiper positions. It operates on a single 2.7V to 5.5V supply with a maximum static current of 1.5µA. The device features a one-time programmable (OTP) function allowing users to define the power-on reset position or lock the interface permanently. It utilizes a simple 2-wire serial interface for control and is housed in an 8-pin µMAX package, rated for operation from -40°C to +85°C.
Feature Summary
- One-Time Programmable (OTP) capability for user-defined power-on reset position or permanent interface lockout
- Linear taper with 32 tap positions and 10kΩ end-to-end resistance
- Ultra-low static supply current of 1.5µA (max)
- Simple 2-wire serial interface (CS, U/D) for wiper adjustment
Applications
- Mechanical potentiometer replacement in space-constrained designs
- Products requiring factory calibration with fixed post-programming settings
- Battery-powered systems requiring minimal quiescent current
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature range. Ensure that any assumed functional differences based solely on suffix variations are validated by the datasheet before procurement.
Selection Notes
Select the MAX5429EUA+ when a 10kΩ resistance value is required. Compare against MAX5427EUA+ (100kΩ) and MAX5428EUA+ (50kΩ) if different resistance values are needed. Confirm that the 32-position resolution meets the application requirements compared to higher-resolution alternatives.
Part Context
The MAX5429EUA+ belongs to the MAX5427/MAX5428/MAX5429 family of one-time programmable, linear-taper digital potentiometers. These devices share identical pinouts and operational characteristics, differing primarily in their end-to-end resistance values (100kΩ, 50kΩ, and 10kΩ respectively).
Replacement Considerations
Direct replacements within the same family include MAX5427EUA+ (100kΩ) and MAX5428EUA+ (50kΩ), provided the resistance value difference is acceptable for the circuit design.
