Overview
The MAX5389LAUD+T is a dual, 256-tap, volatile, low-voltage linear taper digital potentiometer manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +2.6V to +5.5V supply with a quiescent current of less than 1μA. The device features an up/down interface and offers three end-to-end resistance values: 10kΩ, 50kΩ, and 100kΩ. It includes a power-on reset that sets the wiper to midscale and maintains a low temperature coefficient of 35ppm/°C. The component is specified for operation across the automotive temperature range of -40°C to +125°C.
Feature Summary
- Dual 256-Tap Linear Taper Positions
- Single +2.6V to +5.5V Supply Operation
- Low (< 1μA) Quiescent Supply Current
- Up/Down Interface
Applications
- Audio Mixing
- Mechanical Potentiometer Replacement
- Low-Drift Programmable Filters and Amplifiers
- Adjustable Voltage References/Linear Regulators
- Programmable Delays and Time Constants
Procurement Notes
Verify the specific suffix 'AUD+' against official documentation to confirm the 10kΩ resistance value and lead-free/RoHS compliance status. Ensure the package type matches the required 14-pin TSSOP footprint. Confirm availability through authorized distributors as stock levels fluctuate.
Selection Notes
Select this component when a dual-channel digital potentiometer with low power consumption and wide operating voltage is required. The 10kΩ resistance value suits applications needing moderate impedance. Verify that the volatile memory architecture aligns with system requirements, as settings are lost upon power loss.
Part Context
The MAX5389 series includes variants with different resistance values: MAX5389MAUD+ (50kΩ) and MAX5389NAUD+ (100kΩ). All share the same 14-pin TSSOP package and functional specifications. The 'L' in LAUD indicates the 10kΩ variant.
Replacement Considerations
Direct substitutes include MAX5389MAUD+ and MAX5389NAUD+ if resistance tolerance allows. Other dual digital potentiometers may require interface and pinout verification.
