Frequently Asked Questions
What resistance values are available in the MCP45HV51 family, and when should the 100 kΩ variant be chosen?
The MCP45HV51 family offers 5 kΩ, 10 kΩ, 50 kΩ, and 100 kΩ resistor array variants. The 100 kΩ option is preferred in high-impedance signal-conditioning circuits or low-current bias adjustments where lower resistance values would draw excessive current from the source.
How does the 8-bit resolution of MCP45HV51-104E/MQ translate to step resolution across 100 kΩ?
With 8-bit resolution and 256 steps across a 100 kΩ range, each wiper step equals approximately 392 Ω. This level of granularity is suitable for fine trim adjustments in sensor calibration and gain-setting circuits operating at low bandwidths around 0.024 kHz.
What package and environmental compliance data should be reviewed before specifying MCP45HV51-104E/MQ in a new industrial design?
MCP45HV51-104E/MQ is housed in a 20-pin QFN package (JESD-30: S-PQCC-N20) and carries JESD-609 e3 for lead-free compliance. With a YTEOL of 13 years and a 6-week factory lead time, it offers solid supply chain predictability for long-lifecycle industrial programs.
