Ultra-precision 5 V operational amplifiers
Focus on precision, low current consumption, and high stability
High accuracy op amps enabling enhanced performance and energy saving
Today sensors are everywhere and we need to constantly measure almost everything (weight, UV, temperature, speed, current, etc.). Even though we live in an increasingly digital world, most sensors are still purely analog and generally provide an extremely small signal. The challenge is to deal with low-amplitude signals and safely transfer them into the digital domain without introducing any error. This is made possible by choosing the proper operational amplifier that perfectly fits the need for precision. ST offers the TSZ series with low-power, zero-drift operational amplifiers in space-saving packages for both automotive and industrial applications. They use a chopper-stabilized architecture that provides very-low offset voltages and near-zero drift.
