Frequently Asked Questions
How accurate is the MCP1502T-25E/CHY reference voltage, and is ±0.1% sufficient for 12-bit ADC applications?
The MCP1502T-25E/CHY provides a fixed 2.5V output with ±0.1% initial accuracy, equating to ±2.5 mV worst-case error. For a 12-bit ADC with 4096 counts across 2.5V, one LSB represents approximately 0.61 mV, so the reference error is within about 4 LSBs — acceptable for most industrial measurement applications.
Can the MCP1502T-25E/CHY supply enough current to drive both an ADC reference input and a companion DAC simultaneously?
The device supports up to 20 mA (0.03 A maximum) output current, which comfortably powers multiple low-current reference inputs in parallel. Typical ADC and DAC reference pins draw 100 µA to 1 mA, so the 20 mA budget allows driving several ICs from a single MCP1502T-25E/CHY instance.
For a board redesign replacing a through-hole reference with a surface-mount device, how compact is the MCP1502T-25E/CHY footprint?
The MCP1502T-25E/CHY comes in a SOT-23-6 package with only 6 pins, occupying approximately 1.6 mm × 2.9 mm of PCB area. This is significantly smaller than TO-92 through-hole references, enabling density improvements on mixed-signal PCBs while maintaining the same 2.5V reference output.
