Overview
The MAX5460EXK-T is a single-channel digital potentiometer featuring 32 tap positions and a nominal resistance of 100 kΩ. It operates within a supply voltage range of 2.7 V to 5.5 V, consuming a typical current of 24 µA. The device utilizes an Up/Down (U/D, CS) serial interface for control and employs volatile memory to retain wiper position during power cycles. It is housed in a compact SC-70-5 surface-mount package and supports operation across an extended temperature range of -40°C to +85°C.
Feature Summary
- Compact SC-70-5 surface-mount packaging designed for space-constrained applications
- Up/Down serial interface allows simple two-wire control without complex protocol overhead
- Low power consumption suitable for battery-operated or energy-efficient systems
Applications
- Portable consumer electronics requiring volume or gain adjustment
- Battery-powered instrumentation with limited power budgets
- Industrial control systems needing remote resistance tuning
Procurement Notes
Verify the specific suffix 'T' indicates tape-and-reel packaging configuration when ordering. Confirm that the 'E' designation corresponds to the industrial temperature grade (-40°C to +85°C). Ensure compatibility with the 2.7V–5.5V supply range for your target application environment before finalizing procurement.
Selection Notes
Select this component when a high-resistance value (100 kΩ) is required alongside minimal footprint constraints. The volatile memory characteristic necessitates external retention strategies if state preservation during power loss is critical. Consider the ±25% tolerance and 35 ppm/°C temperature coefficient for precision requirements in signal conditioning paths.
Part Context
This part belongs to the Maxim Integrated FleaPot family of digital potentiometers, characterized by ultra-small packages and low power usage. It serves as a direct replacement for traditional mechanical potentiometers in automated calibration and user-adjustable settings where physical knobs are impractical.
Replacement Considerations
The MAX5460EXK+T is a lead-free variant of the same functional device. Cross-reference pinout compatibility when substituting with other 32-tap digital potentiometers from different manufacturers.
