- Non-volatile EEPROM memory retains wiper position across power cycles without additional storage components
- INCREMENT/DECREMENT control interface for simple up/down wiper position control with minimal pin count
- 4 kHz nominal bandwidth supporting audio tone and low-frequency signal conditioning applications
- Tiny SOT-23-6 package measuring only 1.6 mm × 2.9 mm for ultra-compact PCB designs
Applications
The MCP4022T-202E/CH is well-suited for portable and battery-powered devices requiring persistent analog settings such as volume controls, brightness adjustments, and sensor offset calibration, where its non-volatile memory retains the 64-step wiper position after power-off. Its tiny SOT-23-6 package and 2.1 kΩ resistance value make it practical for low-power op-amp gain trim circuits and LCD contrast adjusters in handheld instruments. The simple INCREMENT/DECREMENT interface connects directly to GPIO pins of any microcontroller, enabling software-controlled analog tuning without a dedicated SPI or I2C bus.

Frequently Asked Questions
How many resistance steps does the MCP4022T-202E/CH offer, and what is the resistance per step for fine-grain analog adjustment?
The MCP4022T-202E/CH provides 64 discrete wiper positions over a 2.1 kΩ end-to-end resistance, yielding approximately 33 Ω per step. This resolution allows fine-grained analog trimming in gain-setting and calibration circuits, with the non-volatile EEPROM ensuring the selected position is retained after each power cycle without re-initialization.
What is the bandwidth of the MCP4022T-202E/CH, and which signal frequency ranges does it support reliably?
The MCP4022T-202E/CH has a nominal bandwidth of 4 kHz, meaning it accurately passes analog signals up to approximately 4 kHz through the resistive element. This covers audio frequency tone control and low-frequency sensor signal conditioning tasks while filtering out higher-frequency noise, making it appropriate for audio bass/treble adjustment and slow feedback loop trim applications.
Does the non-volatile memory of the MCP4022T-202E/CH eliminate the need for a microcontroller to re-initialize the wiper position on startup?
Yes, the internal EEPROM of the MCP4022T-202E/CH stores the last programmed wiper position and restores it automatically on power-up, eliminating any firmware initialization routine. This reduces startup latency and simplifies embedded software, particularly important in systems where the analog setting must be immediately valid within microseconds of supply rail stabilization.
For a space-constrained wearable PCB, how does the SOT-23-6 package of the MCP4022T-202E/CH compare to SOIC-8 digital potentiometers?
The SOT-23-6 package of the MCP4022T-202E/CH occupies approximately 4.6 mm² (1.6 mm × 2.9 mm), compared to roughly 30 mm² for an SOIC-8 package, making it about 6.5x smaller. This size advantage is critical in wearable electronics and hearing aid designs where PCB real estate is severely constrained and 64-step resolution over 2.1 kΩ fully meets the application requirement.
