STMicroelectronics has a wide range of Op Amps, including both industry-standard and high-performance Op Amps dedicated to the challenging industrial, automotive, and consumer markets.
Using innovative design techniques and close control of key parameters, STMicroelectronics can also offer upgraded-performance versions of industry-standard devices. ST‘s portfolio is continuously growing in order to offer solutions to electronic designers for many applications and is the best choice for longevity, robustness, and performance.
Sensors in today’s world are used extensively to measure weight, read temperature, identify VOC, control speed, and more. Even though we live in an increasingly digital world, many sensors today are bound to operate in the analog domain. And most of them provide an extremely small signal that needs to be amplified. Precision Operational amplifiers are the primary link between these analog sensors and the digital world.
