Frequently Asked Questions
How does the non-volatile memory in MCP4442-502E/ST benefit system designs that lose power unexpectedly?
The non-volatile memory in MCP4442-502E/ST stores the wiper position for each of the 4 channels, so settings are retained after power removal. This eliminates the need for a host microcontroller to reconfigure the 5 kΩ potentiometer on every power-up, reducing startup time and firmware complexity in industrial and embedded systems.
What I2C bus speeds does MCP4442-502E/ST support, and how many devices can share one bus?
MCP4442-502E/ST communicates over a 2-wire I2C interface compatible with standard 100 kHz and fast 400 kHz bus speeds. Multiple MCP4442 devices can share the same bus through address pin configuration, enabling up to 8 devices on a single I2C bus for multi-channel or multi-zone resistance control applications.
For a 14-pin TSSOP board layout, how many resistance adjustment channels are available and what is the wiper resolution?
In the 14-pin TSSOP package, MCP4442-502E/ST provides 4 fully independent digital potentiometer channels. Each channel supports 129 wiper positions across a 5 kΩ range, giving a step resolution of approximately 39 Ω per step, suitable for precise analog trimming and calibration tasks on compact PCBs.
