Frequently Asked Questions

What is the output reference voltage of the MCP1525-I/TO and how accurate is it?

The MCP1525-I/TO provides a fixed 2.5V output reference with an initial accuracy of ±0.5% (±12.5 mV), making it suitable for 10-bit to 12-bit ADC reference applications where tight voltage tolerance is required.

Over what temperature range does the MCP1525-I/TO maintain its reference accuracy?

The MCP1525-I/TO is rated for an operating temperature range of -40°C to +125°C, and its low temperature coefficient ensures the 2.5V reference remains stable enough for industrial measurement and control circuits across that full range.

Can the MCP1525-I/TO be used directly as a voltage reference for a 12-bit ADC in a 3.3V system?

Yes. The MCP1525-I/TO outputs 2.5V, which is within the input range of most 12-bit ADCs powered from a 3.3V supply. The device needs only a small bypass capacitor of typically 100 nF on the output to maintain stability under dynamic load.

How does the TO-92-3 package of the MCP1525-I/TO compare to SOT-23 alternatives for prototyping?

The TO-92-3 through-hole package has 3 pins on a 1.27 mm pitch and is ideal for breadboard prototyping and manual soldering. SOT-23 SMD variants are smaller at roughly 1.6 mm x 2.9 mm but require SMT assembly, so the TO-92-3 is preferred in low-volume or prototype builds.
