Frequently Asked Questions
What initial accuracy and temperature drift does the MCP1502T-33E/CHY provide for a 16-bit ADC reference application?
The MCP1502T-33E/CHY offers 0.1% initial accuracy, equivalent to approximately 3.3 mV worst-case error at 3.3 V, and a 50 ppm/°C temperature coefficient. Over a 100°C operating range this adds roughly 16.5 mV of drift, which limits it to 12-bit effective accuracy without external trimming, but is sufficient for many 12-bit industrial ADC reference requirements.
How much output current can the MCP1502T-33E/CHY supply to downstream loads such as an ADC and a microcontroller I/O rail?
The MCP1502T-33E/CHY sources up to 30 mA continuously, enough to simultaneously power a 12-bit ADC reference input drawing under 1 mA and several logic gate pull-up resistors. This 30 mA rating avoids external buffer op-amps in most single-board sensor designs, reducing BOM cost and component count by one or two parts.
For a board with limited routing space, how does the SOT-23-6 package of the MCP1502T-33E/CHY compare to larger reference IC packages?
The SOT-23-6 package measures approximately 2.9 mm × 1.6 mm, roughly one-sixth the footprint of an 8-pin SOIC package at about 5 mm × 4 mm. This compact size allows the MCP1502T-33E/CHY to fit near an ADC within a tight layout, minimizing reference trace length and reducing parasitic noise pickup in high-resolution measurement circuits.
