Key Features
- Quad zero-drift op amp with near-zero offset voltage drift over temperature
- 103 dB minimum common-mode rejection ratio for superior noise immunity
- Ultra-low bias current of 50 pA max enabling high-impedance sensor interfaces
- TSSOP-14 package integrating 4 amplifiers to reduce BOM count and PCB area
- Extended industrial temperature range for reliable operation in harsh environments
Applications
The MCP6V79T-E/ST is designed for precision data acquisition systems, industrial sensor signal conditioning, and medical instrumentation that require stable, low-drift amplification over a wide temperature range. Its zero-drift architecture eliminates the need for external offset trimming in strain gauge bridges, thermocouple amplifiers, and weigh-scale front-ends. The quad configuration reduces component count in multichannel acquisition boards for process control and test equipment.

Frequently Asked Questions
How does the zero-drift architecture of MCP6V79T-E/ST improve measurement accuracy over temperature?
Zero-drift op amps use a continuous auto-correction technique that keeps input offset voltage near 0µV across the full temperature range, unlike standard op amps whose offset can drift by several µV per °C. For the MCP6V79T-E/ST, this means strain gauge and thermocouple amplifier circuits maintain accuracy without periodic recalibration even across industrial temperature swings from -40°C to +125°C.
What makes the 103 dB CMRR specification of the MCP6V79T-E/ST valuable for industrial sensor designs?
A CMRR of 103 dB means that common-mode noise—such as 50Hz or 60Hz mains interference present on industrial sensor cables—is attenuated by a factor of over 100,000:1 relative to the differential signal. This allows the MCP6V79T-E/ST to amplify millivolt-level bridge sensor outputs accurately even in noisy factory environments with strong electromagnetic interference.
When is the quad MCP6V79T-E/ST preferred over four discrete single op amps in a design?
Integrating 4 zero-drift channels in a single TSSOP-14 package reduces PCB area by approximately 60% compared to four separate SOT-23-5 devices, while cutting BOM lines and improving thermal matching between channels. This makes MCP6V79T-E/ST the better choice for multichannel data acquisition cards, 4-20mA industrial transmitters, and portable medical monitors where board space and component count are at a premium.
