STMicroelectronics’ high-accuracy TSZ151 operational amplifiers have very low offset voltage with minimal temperature drift, bringing enhanced accuracy and stability to circuits for sensor interfacing, signal conditioning, and current measurement.
An extremely low input offset voltage (Vio) is the defining parameter of a high-accuracy operational amplifier (op amp). The TSZ151 has Vio less than 7µV at 25°C. Moreover, the value remains stable, below 10µV, over the full specified temperature range, from -40°C to 125°C. Its high stability minimizes reliance on periodic recalibration, enhancing availability of the end product throughout its lifetime.
With gain-bandwidth of 1.6MHz and drawing just 210μA at 5V, the TSZ151 sits between ST’s 400kHz TSZ121 and 3MHz TSZ181, giving designers more choice and flexibility to optimize speed and power consumption. The TSZ151 combines its excellent speed-to-power ratio with ultra-low maximum input bias current of 300pA (more info).
