Key Features
- 4 independent 100 kΩ potentiometer channels in a single 14-pin TSSOP package replace 4 discrete mechanical trimmers, consolidating multi-axis calibration circuits onto one IC
- 256-step (8-bit) wiper resolution per channel delivers approximately 391 Ω per step for precise gain, offset, and filter tuning via SPI interface
- Non-volatile wiper position storage retains settings through power cycles, eliminating the need for microcontroller-driven re-initialization at every system startup
Applications
MCP4362-104E/ST is used in instrumentation and test equipment requiring multiple software-controlled resistance adjustments, such as multi-channel sensor offset calibration and programmable gain amplifier stages. Its 4-channel integration with non-volatile memory suits industrial control panels and communication hardware where potentiometer positions must persist across power cycles. The 14-pin TSSOP package fits standard analog circuit board footprints alongside op-amps and ADCs in mixed-signal designs.

Frequently Asked Questions
How many independent resistance channels does MCP4362-104E/ST provide, and what end-to-end resistance does each offer?
MCP4362-104E/ST provides 4 independent potentiometer channels, each with a 100 kΩ end-to-end resistance and 256 wiper positions. This gives a step resolution of approximately 391 Ω per step per channel. Having 4 channels in one 14-pin TSSOP IC replaces 4 separate single-channel digital potentiometers, reducing BOM count and PCB area in multi-axis calibration and filter-tuning circuits.
Does MCP4362-104E/ST retain its wiper position after power is removed, and why does that matter in field-deployed equipment?
Yes, MCP4362-104E/ST stores wiper positions in non-volatile EEPROM memory that survives power loss. In field-deployed equipment such as industrial transmitters or remote sensor nodes, this means the last calibrated 100 kΩ setting is immediately restored at power-up without requiring the host microcontroller to re-transmit calibration values, reducing startup time and eliminating calibration drift from missed re-initialization events.
What serial interface does MCP4362-104E/ST use, and how does SPI control compare to I2C for high-speed updates?
MCP4362-104E/ST uses a 3-wire SPI serial interface, which supports clock rates typically above 10 MHz, compared to I2C's standard 400 kHz fast-mode limit. For applications that need rapid wiper updates — such as adaptive filter coefficient adjustments or real-time signal path switching — SPI's higher throughput allows all 4 channels of the 100 kΩ potentiometer to be updated within a few microseconds, versus tens of microseconds over I2C.
When would MCP4362-104E/ST be preferred over MCP4262 or other 2-channel variants in a design?
MCP4362-104E/ST is preferred when a design requires 4 independent 100 kΩ adjustment channels, such as balancing a 4-element Wheatstone bridge, trimming 4 differential amplifier stages, or calibrating multi-sensor arrays. Using MCP4362's quad-channel integration avoids sourcing and assembling 2 dual-channel ICs, cutting component count by at least 1 package and reducing 14-pin footprint overhead compared to running two MCP4262 devices side by side.
