Overview
The MAX5464ESA is a single-channel digital potentiometer IC from the FleaPot series, manufactured by Analog Devices / Maxim Integrated. It features a 50 kOhm resistance value with a linear taper and offers 32 adjustable taps for precise resistance control. The device operates on a single supply voltage ranging from 2.7 V to 5.5 V, drawing a typical operating current of 24 uA. It utilizes a 2-wire serial interface for communication and includes volatile wiper memory to retain settings during power cycles. Packaged in an 8-pin SOIC format, it supports an industrial temperature range from -40°C to +85°C.
Feature Summary
- Single-channel digital potentiometer with 50 kOhm nominal resistance and linear taper.
- 32-tap resolution controlled via a standard 2-wire serial interface.
- Low power consumption with 24 uA operating current at 2.7 V to 5.5 V supply.
- Volatile wiper memory retains position only while powered.
Applications
- Programmable gain amplifiers requiring adjustable resistance ratios.
- Voltage divider circuits for reference voltage adjustment.
- Digital volume control in audio signal paths.
- Calibration of sensor bias currents or offsets.
Procurement Notes
Verify the specific suffix 'ESA' confirms the SOIC-8 package and commercial/industrial temperature grade. Confirm RoHS compliance status through official documentation as '+T' or '+' suffixes may indicate lead-free variants. Check for obsolescence notices or limited availability directly from Analog Devices distributors, as stock levels fluctuate.
Selection Notes
Select this component when a single, low-power digital pot with 50 kOhm resistance is required. Ensure the system can tolerate volatile memory if power loss resets the wiper position. Verify that the 2-wire interface (Clock/Data) fits the available microcontroller pins. Compare against the MAX5466 series if a smaller SOT-23-5 package or different resistance values like 10 kOhm are preferred.
Part Context
This part belongs to the MAX546x FleaPot family, designed for space-constrained applications. It serves as a solid-state replacement for mechanical potentiometers in systems where remote programming or automated calibration is necessary. The ESA variant specifically denotes the surface-mount SOIC-8 packaging option within this product line.
Replacement Considerations
Direct pin-compatible alternatives within the same family include the MAX5464EUK+ (SOT-23-5 package) for size reduction, though pinouts differ. Cross-family replacements like the DS1802 series offer similar functionality but may require interface adjustments. Always verify electrical parameters such as tolerance (+/- 25%) and temperature coefficient before substitution.
