Overview
The MAX5392LAUE+ is a dual, volatile, low-voltage digital potentiometer featuring two independent 256-tap linear taper resistors with an end-to-end resistance of 10kΩ. It operates from a single +1.7V to +5.5V supply and includes an internal charge pump to maintain wiper resistance below 200Ω at low voltages. The device utilizes an I²C-compatible serial interface for control and offers a low quiescent current of 12µA. It provides a wide operating temperature range of -40°C to +125°C and is housed in a 16-pin TSSOP package.
Feature Summary
- Dual 256-tap linear taper digital potentiometers with 10kΩ end-to-end resistance
- I²C-compatible serial interface with up to eight devices addressable on one bus
- Internal charge pump ensures wiper resistance <200Ω down to 1.7V supply
- Wipers initialize to midscale (80h) upon power-up
Applications
- Mechanical potentiometer replacement in portable electronics
- Adjustable voltage references and linear regulators
- Offset and gain control in signal conditioning circuits
- LCD bias control applications
Procurement Notes
Verify the component status as discontinued or obsolete through official manufacturer channels before design finalization. Confirm RoHS compliance via the '+' suffix designation. Ensure adequate lead time for alternative sourcing if this specific package variant is no longer in active production cycles.
Selection Notes
Select the MAX5392LAUE+ specifically for its 10kΩ resistance value; other variants include 50kΩ and 100kΩ options. This device is volatile, meaning settings are lost upon power loss. Verify that the system requires an I²C interface and that the -40°C to +125°C automotive temperature range meets environmental requirements.
Part Context
This component belongs to the MAX5392 family of dual digital potentiometers manufactured by Maxim Integrated (now Analog Devices Inc.). The 'L' suffix denotes the 10kΩ resistance option, while 'U' indicates the 16-pin TSSOP package. The '+' suffix confirms lead-free/RoHS-compliant manufacturing.
Replacement Considerations
Direct pin-compatible replacements within the same family include MAX5392MAUE+ (50kΩ) and MAX5392NAUE+ (100kΩ). For different resistance values, verify that the increased wiper resistance associated with higher ohmic ratings does not exceed circuit limits.
