Overview
The MAX5451EUD+ is a dual digital potentiometer featuring two independent 3-terminal variable resistors, each with 256 digitally controlled wiper positions. It operates on a single supply voltage ranging from +2.7V to +5.5V and consumes an ultra-low supply current of 0.1µA. The device utilizes an up/down interface for glitchless switching between resistor taps. Key electrical characteristics include a 10kΩ end-to-end resistance with ±25% tolerance, a temperature coefficient of 35ppm/°C, and a power-on reset that sets the wiper to midscale (position 127). It is housed in a 14-pin TSSOP package.
Feature Summary
- Dual 3-terminal potentiometers with 256 tap positions
- Up/Down interface for glitchless switching
- Ultra-low 0.1µA supply current
- Power-on reset sets wiper to midscale
Applications
- Mechanical Potentiometer Replacement
- Low-Drift Programmable-Gain Amplifier (PGA)
- Volume Control
- LCD Screen Adjustment
- Adjustable Voltage References
Procurement Notes
Verify component authenticity through authorized distributors or manufacturer channels. Confirm RoHS compliance status as indicated in official documentation. Ensure the ordering suffix matches the required package type and temperature range specifications before procurement.
Selection Notes
Select the MAX5451EUD+ when dual independent 3-terminal potentiometers are required. Choose this model over the MAX5450/MAX5452 variants if separate control of two potentiometers is necessary rather than coupled variable resistors. Verify that the 10kΩ resistance value fits the circuit design requirements.
Part Context
The MAX5451EUD+ belongs to the MAX5450–MAX5455 family of dual digital potentiometers manufactured by Analog Devices / Maxim Integrated. This family provides low-cost, low-power solutions for replacing mechanical potentiometers in space-constrained applications requiring digital adjustment capabilities.
Replacement Considerations
The MAX5453EUD+ serves as a direct functional substitute within the same family, differing only in its 50kΩ resistance value. The MAX5455EUD+ is another alternative offering 100kΩ resistance. Ensure the replacement part's resistance value aligns with the specific circuit requirements.
