Frequently Asked Questions
How many wiper positions does the MCP4023T-202E/CH support and what is its full-scale resistance?
The MCP4023T-202E/CH provides 64 linear wiper positions across a 2.1 kΩ end-to-end resistance, giving approximately 33 Ω per step. This resolution is suitable for fine gain or offset adjustment in signal conditioning circuits.
Does the MCP4023T-202E/CH retain its wiper setting when power is removed?
Yes. The MCP4023T-202E/CH includes non-volatile memory that retains the last programmed wiper position after power is cycled, eliminating the need for the host microcontroller to reprogram the device on every startup.
For a compact audio volume control circuit, what package and bandwidth does the MCP4023T-202E/CH offer?
The MCP4023T-202E/CH is housed in a 6-pin SOT-23 package with a 4 kHz nominal bandwidth, making it a practical choice for audio-path volume control or tone adjustment in portable and handheld consumer devices.
What serial interface does MCP4023T-202E/CH use, and how does it compare to SPI-based digital potentiometers?
The MCP4023T-202E/CH uses a simple 2-wire increment/decrement interface rather than SPI or I2C. This reduces GPIO usage to just 2 lines and is well-suited for designs where only incremental wiper changes are needed, though it does not support direct register writes like SPI parts.
