Key Features
- Non-volatile memory stores wiper position across power cycles, eliminating initialization code on every startup
- 7-bit resolution with 128 wiper steps and 100 kΩ end-to-end resistance for fine-grained analog adjustment via I2C
- Low 0.1 kHz bandwidth and compact 8-pin MSOP package suit low-frequency signal conditioning and bias trimming applications
Applications
MCP4541-104E/MS is used in precision analog circuits where software-controlled resistance trimming is needed, such as LCD contrast adjustment, audio volume control, and sensor signal offset compensation. The non-volatile memory ensures the last wiper setting is retained through power cycles, ideal for factory calibration of instruments where manual re-adjustment is not practical. Its I2C interface allows multiple devices sharing a 2-wire bus for multi-channel trimming in space-constrained designs.

Frequently Asked Questions
Does MCP4541-104E/MS retain its wiper position after power is removed, and how many write cycles does the NV memory support?
Yes, MCP4541-104E/MS stores the wiper position in non-volatile EEPROM memory, retaining the setting after power is removed. The non-volatile memory is rated for over 100,000 write cycles and a 40-year data retention period, making it suitable for factory-calibrated instruments and field-adjustable equipment that must maintain settings without a battery backup.
How many wiper positions does MCP4541-104E/MS provide, and what is the step resolution across 100 kΩ?
MCP4541-104E/MS offers 128 wiper steps over its 100 kΩ end-to-end resistance, giving approximately 781 Ω per step. This 7-bit resolution allows fine analog control of gain, offset, or attenuation in audio, sensor, and reference circuits, controllable via simple increment/decrement I2C commands without needing to specify absolute register values.
Can MCP4541-104E/MS be used with a 3.3 V microcontroller I2C bus, and what supply voltage range does it support?
MCP4541-104E/MS operates from 1.8 V to 5.5 V, making it directly compatible with 3.3 V and 5 V microcontroller I2C buses without level-shifters. The I2C interface supports 100 kHz standard mode and 400 kHz fast mode, and up to 8 devices may share the same bus using the hardware address pins, enabling multi-channel trimming in a single design.
