Key Features
- 5 kΩ (502) end-to-end resistance with nonvolatile memory to retain wiper position across power cycles
- 2 kHz bandwidth supports audio and low-frequency signal conditioning applications
- Increment/decrement control interface via I2C serial bus for simple wiper adjustment
- SOT-23-6 package with minimal 6-pin footprint for space-constrained designs
- Pb-free, RoHS-compliant construction with 7-week factory lead time
Applications
The MCP4022T-502E/CH is used in applications requiring digitally controlled analog resistance such as audio volume control, LCD contrast adjustment, sensor calibration, and programmable gain amplifiers. Its nonvolatile memory makes it ideal for designs where the wiper setting must persist without a host microcontroller at power-up, such as in industrial calibration equipment and portable consumer devices. The compact SOT-23-6 package suits space-constrained PCBs in wearables, handheld instruments, and IoT sensor nodes.

Frequently Asked Questions
How does the nonvolatile memory in MCP4022T-502E/CH benefit power-cycling applications?
The MCP4022T-502E/CH stores the wiper position in nonvolatile memory, so a 5 kΩ resistance setting is retained across power cycles without requiring a microcontroller to reprogram it at startup, which simplifies firmware and reduces initialization latency in calibration and gain-control designs.
What bandwidth does MCP4022T-502E/CH support, and is that sufficient for audio frequency signal paths?
MCP4022T-502E/CH has a 2 kHz bandwidth, which covers most audio-frequency control tasks such as volume adjustment, tone control, and low-frequency filter tuning, though it is not suitable for high-frequency RF or wideband signal paths above a few kilohertz.
For a compact PCB design, what footprint and assembly benefits does the SOT-23-6 package offer?
The SOT-23-6 package provides 6 pins in a very small surface-mount footprint compatible with standard SMT reflow assembly, enabling the MCP4022T-502E/CH to fit on densely populated boards in portable instruments, IoT nodes, or wearable devices where board area below 5 mm x 5 mm is a constraint.
When would MCP4022T-502E/CH be preferred over a volatile digital potentiometer in a production design?
MCP4022T-502E/CH is preferred when the end-to-end 5 kΩ trim setting must survive a power loss without re-calibration, such as in field-deployed sensors or factory-calibrated analog front ends where re-running a calibration routine on every boot would be impractical or add unacceptable startup time.
