Key Features
- Zero-drift architecture eliminates offset voltage drift over temperature, enabling stable DC precision measurements without periodic calibration
- 134 dB typical common-mode rejection ratio (111 dB min) rejects power-supply and ground noise in high-resolution sensor front-ends
- Ultra-low bias current max of 0.00005 µA minimises charge injection on high-impedance photodiode and electrochemical sensor inputs
Applications
MCP6V67T-E/MS is ideal for precision weigh-scale bridges and thermocouple amplifiers where offset drift over the extended -40°C to +125°C temperature range must remain below 1 µV/°C. Its dual-channel, zero-drift topology also suits current-sense amplification in battery management systems and medical instrumentation where long-term accuracy without trimming is critical.

Frequently Asked Questions
How does the zero-drift architecture in MCP6V67T-E/MS benefit long-term precision measurement systems?
Zero-drift op amps like MCP6V67T-E/MS use internal auto-zeroing or chopper stabilisation to continuously correct input offset voltage, keeping drift well below 1 µV/°C across the full E-grade temperature range of -40°C to +125°C. This means a weigh-scale or RTD bridge circuit can operate for thousands of hours without recalibration, unlike standard op amps that drift with temperature cycles.
What is the significance of the 111 dB minimum CMRR for industrial sensor applications using MCP6V67T-E/MS?
A 111 dB minimum CMRR means common-mode interference (e.g., 50 Hz or 60 Hz mains noise on a Wheatstone bridge output) is attenuated by a factor exceeding 350,000:1. In practice, for a sensor supplying a 10 mV differential signal riding on a 2 V common-mode voltage, the MCP6V67T-E/MS introduces less than 6 nV of error from that 2 V noise—critical for 16-bit or 24-bit ADC front-ends.
For a dual-channel design, how does MCP6V67T-E/MS compare to using two single-channel zero-drift op amps in MSOP-8?
Integrating both channels into a single MSOP-8 package halves the component count and reduces PCB area by roughly 50% compared to two separate SOT-23-5 or SC-70 zero-drift amplifiers. The matched dual channels also share a common substrate, improving channel-to-channel offset tracking to within a few microvolts over temperature—an advantage in differential bridge amplifier configurations where gain-matching across 2 channels matters.
Which procurement lead time should engineers plan for when ordering MCP6V67T-E/MS in production volumes?
Microchip quotes a factory lead time of 11 weeks for MCP6V67T-E/MS in standard production volumes. Design teams should build at least a 13-week buffer into their BOM procurement schedule to absorb shipping and inspection time, particularly for medical or industrial builds requiring full lot traceability on E-temperature-grade parts.
