Frequently Asked Questions
How many resistance steps does MCP42010-E/SL offer and what end-to-end resistance does each channel provide?
MCP42010-E/SL offers 256 discrete wiper positions per channel, giving approximately 39 Ω per step on a 10 kΩ end-to-end resistance. This resolution is sufficient for precision gain setting in instrumentation amplifiers and calibration trim circuits where coarse mechanical potentiometers introduce reliability concerns.
Can MCP42010-E/SL control two independent resistances simultaneously, and how does SPI addressing work?
Yes, MCP42010-E/SL contains 2 independent potentiometer channels, each with its own 10 kΩ resistance ladder and 256-position wiper. The 3-wire SPI command byte includes a channel-select field, so both wipers can be updated in a single daisy-chain transaction or addressed individually, making it straightforward to use from any microcontroller with an SPI peripheral.
What bandwidth limitation should designers consider when using MCP42010-E/SL in an active filter or audio signal path?
MCP42010-E/SL has a nominal bandwidth of 1 kHz, which restricts its use to low-frequency signal paths such as audio tone controls or DC bias adjustment loops. At frequencies significantly above 1 kHz, the parasitic capacitance of the resistor array causes the effective resistance to decrease, introducing frequency-dependent gain errors in high-frequency filter designs.
