What are the key features of MCP635-E/UN?
- 24 MHz gain-bandwidth product enabling active filter and signal conditioning up to the audio-to-intermediate frequency range
- Chip-select shutdown pin reduces quiescent current for duty-cycled battery-powered sensor front-ends
- 5 nA maximum input bias current for accurate amplification of high-impedance piezoelectric and electrochemical sensor signals
- 81 dB typical common-mode rejection ratio minimizing power-line noise pickup in single-supply instrumentation circuits
What is MCP635-E/UN used for?
The MCP635-E/UN is suited for active low-pass and bandpass filter stages, sensor signal conditioning, and transimpedance amplifier circuits in portable and industrial measurement equipment. Its chip-select shutdown input is particularly valuable in multiplexed sensor arrays where individual amplifier channels are powered down between sampling intervals to extend battery life. The extended -40°C to +125°C rating ensures reliable operation in outdoor environmental sensors, automotive diagnostics, and industrial process control front-ends.

Frequently Asked Questions
How does the 24 MHz gain-bandwidth product of MCP635-E/UN compare to standard audio-band op-amps in an active filter application?
With a 24 MHz gain-bandwidth product, the MCP635-E/UN can implement a second-order Sallen-Key filter with a 1 MHz cutoff at unity gain, whereas a typical 1 MHz audio op-amp would be bandwidth-limited below 100 kHz at useful closed-loop gains of 10 or more.
What input bias current does the MCP635-E/UN exhibit, and how does it affect transimpedance amplifier accuracy?
The maximum input bias current of 5 nA creates only 5 µV of offset error across a 1 kΩ feedback resistor, making the MCP635-E/UN suitable for photodiode transimpedance amplifiers and pH electrode buffers where sub-10 nA bias is required.
How does the chip-select pin on MCP635-E/UN differ from a standard power-down pin on a conventional dual op-amp?
The chip-select input lets the host MCU disable the amplifier output stage digitally, dropping quiescent current from its active value to a near-zero shutdown level, enabling per-channel power management in multiplexed 8-channel sensor front-ends sampling at 10 Hz or slower rates.
Over what temperature range is the MCP635-E/UN rated for continuous operation in an outdoor sensor node?
Rated for the extended industrial temperature range of -40°C to +125°C, the MCP635-E/UN maintains its 66 dB minimum CMRR and 24 MHz gain-bandwidth across a 165°C span, suitable for outdoor metering enclosures exposed to direct sunlight and cold-climate condensation.
