Overview
The MAX5415EUD+T is a dual linear taper digital potentiometer from the MAX5413/MAX5414/MAX5415 family, manufactured by Analog Devices/Maxim Integrated. It features two independent 3-terminal potentiometers with 256 tap positions and a nominal end-to-end resistance of 100kΩ. The device operates on a single +2.7V to +5.5V supply with an ultra-low 0.1µA supply current. It utilizes a 3-wire SPI-compatible serial interface for wiper control and includes glitchless switching and a power-on reset (POR) that sets the wiper to midscale at power-up.
Feature Summary
- Dual 3-terminal potentiometers with 256 tap positions
- Ultra-low 0.1µA supply current
- +2.7V to +5.5V single-supply operation
- Glitchless switching between resistor taps
- Power-on reset (POR) to midscale position
Applications
- Mechanical Potentiometer Replacement
- Low-Drift Programmable Gain Amplifier (PGA)
- Volume Control
- LCD Screen Adjustment
- Adjustable Voltage Reference
Procurement Notes
Verify the component against official Maxim Integrated datasheets to confirm authenticity and specifications. Ensure the ordering suffix matches the required package and temperature range. Check for RoHS compliance status as indicated in the manufacturer's documentation.
Selection Notes
Select the MAX5415EUD+T when a 100kΩ resistance value is required. Compare with MAX5413 (10kΩ) and MAX5414 (50kΩ) if different resistance values are needed. Consider the low-drift characteristics for precision applications requiring stable temperature coefficients.
Part Context
The MAX5415EUD+T belongs to the MAX5413/MAX5414/MAX5415 family of dual, 256-tap, low-drift digital potentiometers. These devices are designed to replace mechanical potentiometers in space-constrained applications, offering precise digital control over resistance values.
Replacement Considerations
Direct substitutes within the same family include MAX5413EUD+T (10kΩ) and MAX5414EUD+T (50kΩ). Verify pin compatibility and resistance requirements before substitution.
FAQ
