Frequently Asked Questions
How many wiper steps does the MCP45HV51-104E/ST support, and what resistance increment does each step represent?
The MCP45HV51-104E/ST provides 256 discrete wiper positions over a 100 kΩ end-to-end resistor, giving approximately 391 Ω per step. This resolution is sufficient for fine-grained gain control, voltage trimming, and calibration in precision analog circuits.
Which microcontroller interface does the MCP45HV51-104E/ST use, and how many wires does it need for control?
The MCP45HV51-104E/ST uses an I2C 2-wire serial interface, requiring only SDA and SCL lines to communicate with a host microcontroller. This minimizes pin usage and allows multiple devices to share the same bus at up to 400 kHz standard-mode or fast-mode I2C speeds.
What is the lead time and package option for the MCP45HV51-104E/ST in production procurement?
The MCP45HV51-104E/ST is available in a 14-pin TSSOP package and carries a factory lead time of approximately 7 weeks. Procurement teams should plan accordingly and consider buffer stock for production builds, especially given the TSSOP-14 form factor and industrial operating range.
Is the MCP45HV51-104E/ST suitable for audio potentiometer or gain-control applications requiring low noise?
The MCP45HV51-104E/ST can be used in audio and signal-chain gain control where 100 kΩ impedance and 256-step resolution are appropriate. The 0.024 kHz rated bandwidth indicates it is better suited for DC and low-frequency control loops rather than high-fidelity audio paths operating at 20 kHz.
