Frequently Asked Questions
How many independent wiper channels does the MCP4361-502E/ST provide, and what is the step resolution?
The MCP4361-502E/ST integrates 4 independent digital potentiometer channels, each offering 256 steps of resolution over a 5 kΩ end-to-end resistance range, giving fine-grained control in applications such as programmable gain amplifiers.
What control interface does the MCP4361-502E/ST use, and what bandwidth does it support?
It uses a 3-wire SPI serial interface, allowing easy daisy-chain connection to microcontrollers. The AC signal bandwidth is rated at 2 kHz, suitable for audio and low-frequency analog signal processing tasks.
Does the MCP4361-502E/ST retain wiper settings after power is removed?
Yes, the device includes non-volatile EEPROM memory that stores the wiper position for all 4 channels, so calibration offsets or volume settings of 0–255 steps are preserved across power cycles without host intervention.
What package does the MCP4361-502E/ST come in, and how compact is the PCB footprint?
The MCP4361-502E/ST is housed in a TSSOP-20 package with 20 pins on a 0.65 mm pitch, giving a compact footprint of approximately 6.5 mm × 4.4 mm — well suited for space-constrained board designs.
