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, sign conditioning, and present measurement.
A particularly low enter offset voltage (Vio) is the defining parameter of a high-accuracy operational amplifier (op amp). The TSZ151 has Vio lower than 7µV at 25°C. Furthermore, the worth stays steady, under 10µV, over the total specified temperature vary, from -40°C to 125°C. Its excessive stability minimizes reliance on periodic recalibration, enhancing availability of the tip product all through its lifetime.
With gain-bandwidth of 1.6MHz and drawing simply 210μA at 5V, the TSZ151 sits between ST’s 400kHz TSZ121 and 3MHz TSZ181, giving designers extra alternative and suppleness to optimize velocity and energy consumption. The TSZ151 combines its wonderful speed-to-power ratio with ultra-low most enter bias present of 300pA.
Having a minimal working voltage of 1.8V, the TSZ151 could be powered from the identical rail as different ICs within the system, equivalent to a low-voltage microcontroller. The rail-to-rail enter and output assist maximize dynamic vary. The op amp additionally has very low energy consumption, drawing simply 210μA at 5V, whereas the low supply-voltage functionality permits prolonged runtime with a discharged battery.
Leveraging its extensive working temperature vary, from -40°C to +125°C, designers can use the TSZ151 in gear to be deployed in harsh environments and in functions with lengthy mission profiles.Typical makes use of embrace suggestions circuitry in energy provides for industrial, server and telecom-infrastructure functions, and automotive high-accuracy sign conditioning and energy conversion. The TSZ151 is AEC-Q100 certified and is roofed by ST’s rolling 10-year longevity plan that ensures long-term product help.
The TSZ151 is in mass manufacturing now and obtainable in a alternative of tiny SC70-5 and SOT23-5 packages. Free samples can be found at ST’s eStore and pricing begins at $0.58 for 1000 items.
