Useful designer resources for analog signal conditioning applications

MEMS sensors

ST help you find the best operational amplifiers, comparators and current sense amplifiers for your design.

Operational amplifiers play a major role in analog signal conditioning applications. ST’s op amp portfolio includes devices designed to satisfy all the requirements for the latest applications including more complex amplification and filtering, or just for interfacing analog signals with an analog-to-digital converter or a microcontroller for both industrial and automotive standards.

Application examples

industrial sensor Automotive
io-link Industrial
automation Personal electronics
switching Communications, equipment, computers & peripherals

Most of ST’s high-performance op amps come with our 10-year longevity commitment.
