Key Features
- Dual zero-drift op-amp with 140 dB typical CMRR for ultra-low offset error in DC precision measurement
- Sub-picoamp input bias current of 0.00005 µA max minimizes source-impedance errors in high-impedance sensor interfaces
- Voltage-feedback architecture with internal frequency compensation simplifies stability design
- MSOP-8 package enables compact dual-channel layouts with a minimal PCB footprint
Applications
MCP6V97T-E/MS is well suited for precision instrumentation amplifiers, current sensing, and bridge transducer signal conditioning where offset drift over temperature would degrade measurement accuracy. Its 112 dB minimum CMRR makes it ideal for rejecting common-mode noise in industrial sensor front-ends and medical diagnostic equipment operating from -40°C to +125°C. The zero-drift architecture ensures long-term DC accuracy without external trimming or periodic calibration.

Frequently Asked Questions
What CMRR performance does MCP6V97T-E/MS achieve, and why does it matter for bridge sensor applications?
MCP6V97T-E/MS delivers a minimum CMRR of 112 dB and a typical value of 140 dB, which means common-mode interference up to 140 dB larger than the differential signal is rejected. For a Wheatstone bridge running on a 5 V excitation rail with millivolt-level outputs, this level of rejection keeps ground noise and supply ripple from corrupting the measured signal, enabling sub-millivolt resolution without additional filtering.
For a high-impedance electrochemical sensor interface, how does the 0.00005 µA bias current of MCP6V97T-E/MS affect accuracy?
With a maximum input bias current of 0.00005 µA (50 pA) at 25°C, the voltage error across a 10 MΩ source impedance is only 0.5 mV, far below the 1 mV threshold typical in pH or dissolved-oxygen sensor front-ends. This allows direct interfacing with high-impedance electrodes without buffer stages, saving at least 2 components and reducing PCB area.
When is MCP6V97T-E/MS a better choice than a standard precision op-amp for an extended temperature range design?
A zero-drift architecture continuously corrects offset voltage using auto-zeroing or chopper techniques, so the effective input offset stays below a few µV across the full -40°C to +125°C range without any external trim. A conventional precision op-amp with a 1 µV/°C drift would accumulate 165 µV of offset shift over that 165°C span, which can be unacceptable in 12-bit or 16-bit ADC front-ends. MCP6V97T-E/MS eliminates that drift budget entirely.
What is the lead time and package for MCP6V97T-E/MS, and what does the -E/MS suffix indicate?
The factory lead time is 11 weeks, and the device is supplied in an MSOP-8 small-outline package with 8 pins on a 0.65 mm pitch. The -E suffix designates the extended industrial temperature range (-40°C to +125°C), while /MS denotes the MSOP-8 package and tape-and-reel shipping format, which is compatible with standard SMT pick-and-place assembly for volume production.
