What are the key features of MCP4362-103E/ST?
- Quad independent 8-bit digital potentiometer channels with 10 kΩ end-to-end resistance and 256 wiper positions for precise software-controlled resistance adjustment
- Non-volatile EEPROM wiper position storage retaining last programmed resistance value through power cycles without MCU re-initialization
- SPI-compatible 3-wire serial interface supporting daisy-chain multi-device configurations and clock rates up to 10 MHz for fast system integration
What is MCP4362-103E/ST used for?
The MCP4362 suits programmable gain amplifier circuits, DC bias calibration networks, and voltage divider adjustment in precision analog front-ends where software-controlled resistance replacement eliminates mechanical trimmers. Its non-volatile wiper memory enables factory calibration storage and power-cycle resistance retention in industrial sensor transmitters and medical signal conditioning modules. The quad-channel integration in a single TSSOP-14 package reduces board area compared to four discrete digital potentiometer ICs in multi-axis or multi-parameter calibration systems.

Frequently Asked Questions
How many wiper positions and what resistance resolution does the MCP4362 provide per channel?
Each MCP4362 channel provides 256 wiper positions across a 10 kΩ end-to-end resistance, yielding a step resolution of approximately 39 Ω per LSB. This resolution enables gain adjustments of less than 0.4% per step in a voltage divider or programmable gain amplifier circuit, sufficient for factory calibration of 12-bit sensor conditioning networks.
Does the MCP4362 retain its wiper position after power is removed, and how is this achieved?
Yes, the MCP4362 stores wiper positions in on-chip non-volatile EEPROM that retains values for more than 200 years at room temperature and survives at least 100000 write cycles. This allows factory-programmed calibration constants or user-set gain values to persist through power cycling without a host MCU re-sending the resistance settings on every startup.
What SPI clock rate does the MCP4362 support, and how many devices can share a single SPI bus?
The MCP4362 supports SPI clock frequencies up to 10 MHz, enabling rapid wiper position updates in closed-loop control systems. Multiple MCP4362 devices can share a single SPI bus using separate chip-select lines or daisy-chain configuration, allowing a single microcontroller SPI port to control 8 or more quad-channel potentiometers in complex calibration systems with 32 or more adjustment channels.
In which analog calibration applications does the MCP4362 eliminate the need for manual mechanical trimmers?
The MCP4362 replaces mechanical multi-turn trimmers in programmable low-pass filter cutoff frequency adjustment, instrumentation amplifier gain setting, LCD contrast control, and audio equalizer band gain calibration. Factory automated test equipment can write calibration coefficients via SPI in under 1 ms per channel, reducing calibration time from minutes per unit with manual trimmers to milliseconds in high-volume production testing.
How does the quad-channel integration of MCP4362 benefit PCB design compared to using four separate single-channel digital potentiometers?
The MCP4362 integrates 4 independent potentiometer channels in a single TSSOP-14 package measuring 5 mm x 4.4 mm, versus 4 individual SOT-23 single-channel ICs occupying approximately 24 mm² total. This consolidation reduces PCB footprint by over 60%, cuts passive component count, simplifies routing of the shared SPI bus, and lowers BOM cost in multi-channel precision calibration and audio signal processing boards.
