Key Features
- Auto-zero (auto-calibration) architecture eliminates offset voltage drift, achieving near-zero DC error over temperature
- 20 MHz gain-bandwidth product enables wide-bandwidth signal processing in audio and sensor conditioning stages
- Ultra-low 0.005 µA maximum bias current with 84 dB typical CMRR supports high-impedance sensor interfaces
Applications
The MCP622-E/SN is designed for precision signal conditioning applications requiring low offset and drift, such as thermocouple amplifiers, bridge sensor amplifiers, and medical instrumentation front-ends. Its auto-zero architecture continuously corrects offset errors, making it ideal for high-accuracy, low-frequency measurements where DC precision is critical. The dual-amplifier configuration in a compact SOIC-8 package allows two independent signal channels to share a single IC in a differential or cascaded amplifier topology.

Frequently Asked Questions
How does the auto-zero feature of MCP622-E/SN reduce measurement error in precision sensor designs?
The MCP622-E/SN uses an internal auto-zero (chopper-stabilized) technique that continuously samples and cancels the input offset voltage. This reduces effective input offset to near 0 µV and eliminates 1/f (flicker) noise, allowing DC-accurate measurements from sensors such as thermocouples or strain gauges with errors below 1 µV, which is essential in high-resolution 16-bit or 24-bit ADC signal chains.
What signal bandwidth does the MCP622-E/SN provide, and how does it fit into audio or data acquisition designs?
The MCP622-E/SN has a 20 MHz gain-bandwidth product in its voltage-feedback architecture. At a closed-loop gain of 10, this yields a small-signal bandwidth of 2 MHz, sufficient for audio processing up to 20 kHz with large gain margin and for industrial sensor conditioning at sampling rates up to 500 ksps. The frequency compensation feature ensures stability across a wide range of capacitive loads and feedback configurations.
What is the common-mode rejection ratio of the MCP622-E/SN and why does it matter for differential sensor measurements?
The MCP622-E/SN achieves a typical CMRR of 84 dB and a minimum of 68 dB. In a differential measurement setup such as a Wheatstone bridge or a 4-wire RTD, a CMRR of 84 dB means common-mode noise at the input is attenuated by a factor of approximately 16,000, so a 1 V 50 Hz interference signal would contribute less than 63 µV of error at the output, preserving measurement accuracy in electrically noisy industrial environments.
When should MCP622-E/SN be chosen over a standard op-amp in a low-side current sensing circuit?
MCP622-E/SN is preferred over standard op-amps in low-side current sensing when the measured voltage across the sense resistor is in the 1 mV to 10 mV range, because its auto-zero architecture keeps input offset below 5 µV across the extended temperature range (E grade, typically -40°C to +125°C). A standard op-amp with a 1 mV offset would introduce a 10% to 100% measurement error at these small signals, whereas the MCP622 maintains sub-1% accuracy without external trimming.
