What are the key features of MCP633-E/SN?
- 24 MHz gain-bandwidth product enabling wideband signal amplification in active filters and high-speed sensor front-end circuits
- Chip-select (CS) shutdown pin allowing microcontroller-controlled power gating to reduce system quiescent current in duty-cycled applications
- 81 dB typical CMRR with voltage-feedback architecture providing robust rejection of common-mode noise in industrial and instrumentation signal chains
What is MCP633-E/SN used for?
The MCP633-E/SN is suited for active band-pass filters, high-speed transimpedance amplifiers, and sensor signal conditioning circuits that require 24 MHz bandwidth with the option to disable the amplifier via chip-select to save power. Its shutdown feature makes it practical in duty-cycled portable instruments where the analog front-end is powered only during measurement windows, extending battery life. The extended E temperature range and SOIC-8 package support industrial panel meters, process control transmitters, and data acquisition modules.

Frequently Asked Questions
How does the chip-select shutdown feature of the MCP633-E/SN extend battery life in a duty-cycled portable sensor design?
The MCP633-E/SN chip-select pin allows a microcontroller to disable the op-amp between measurement cycles, cutting supply current to near zero during the off period. In a sensor node that samples every 10 seconds with a 1 ms active window, this reduces average supply current by approximately 99.99% compared to always-on operation, significantly extending battery runtime in 3.3 V or 5 V powered portable instruments.
At a closed-loop gain of 4, what signal bandwidth does the MCP633-E/SN support for an active filter stage?
With a 24 MHz gain-bandwidth product, at a closed-loop gain of 4 (12 dB) the MCP633-E/SN delivers approximately 6 MHz of closed-loop bandwidth (24 MHz ÷ 4). This makes it suitable for anti-aliasing filters ahead of ADCs sampling at 1 MHz to 5 MHz, video signal buffering, and wideband sensor amplifiers that must pass frequencies well beyond the audio range.
How does the MCP633-E/SN 81 dB CMRR compare to the 66 dB minimum specification, and which application scenario benefits from the higher typical value?
The 66 dB minimum CMRR guarantees worst-case noise rejection of at least 2 000× across all production units, while the 81 dB typical value represents 112 000× attenuation for most devices. Precision differential measurement circuits, such as ECG front-ends or Wheatstone bridge amplifiers, benefit most from the higher 81 dB typical CMRR because it allows the signal chain to operate without active common-mode trimming in environments with 50 Hz or 60 Hz interference levels up to 1 V.
For a 5 V industrial signal chain, how does the MCP633-E/SN 0.005 µA input bias current affect offset error at high feedback resistance values?
With 0.005 µA maximum average input bias current and a 1 MΩ feedback resistor, the resulting offset error contribution is 5 mV (0.005 µA × 1 MΩ). This is acceptable for most industrial sensor interfaces using feedback resistors up to 200 kΩ, where offset stays below 1 mV, but designers using resistors above 1 MΩ should account for this 5 mV error in the total error budget for precision voltage measurement.
