STMicroelectronics operational amplifiers have low offset, zero temperature drift, and wide gain bandwidth to improve measurement accuracy

 


【Lansheng Technology News】STMicroelectronics' high-precision TSZ151 operational amplifier features extremely low offset voltage and temperature drift, helping to improve the accuracy and stability of sensor interfaces, signal conditioning, and current measurement circuits.


Very low input offset voltage (Vio) is a key parameter for high-precision operational amplifiers (op amps). The input offset voltage of the TSZ151 is less than 7µV at 25°C. The input offset voltage is stable to less than 10µV over the specified temperature range of -40°C to 125°C. High stability helps minimize the number of periodic recalibrations and increases the availability of the end product throughout its life cycle.


The gain bandwidth of TSZ151 is 1.6MHz, and the operating current is only 210μA at 5V voltage. The product is positioned between STMicroelectronics’ 400kHz TSZ121 and 3MHz TSZ181, bringing more choices and more options for designers to optimize speed and power consumption. High flexibility. The TSZ151 combines excellent speed-to-power ratio with low maximum input bias current (300pA).


The TSZ151 operates with a minimum operating voltage of 1.8V, allowing it to share power rails with other ICs in the system, such as low-voltage microcontrollers. Rail-to-rail inputs and outputs help maximize dynamic range. The op amp also has very low power consumption, consuming only 210μA at 5V, and the low supply voltage feature extends battery life.


The wide operating temperature range of -40°C to +125°C allows designers to use the TSZ151 in harsh environments and long load curve applications. Typical applications include feedback circuits in industrial, server and telecommunications infrastructure power supplies, and automotive High-precision signal conditioning and power conversion circuitry. The TSZ151 is AEC-Q100 compliant and enjoys STMicroelectronics’ 10-year rolling product life plan to ensure long-term product support.

What are the Benefits of Power Optimizers?

Image
  Power optimizer for solar panels is a DC/DC converter that is connected to each solar panel in the PV system, turning them into smart modules. By constantly monitoring the maximum production capacity of each individual solar module, optimizers can increase your PV plant energy production – potentially increasing revenue and shortening system payback time. Simply put, the main benefit of power optimizer is that it maximizes the performance of each panel individually. What are the benefits of power optimizers and why are they needed? When installing solar panels, the panels are connected into groups or arrays. In the case of roof-mounted and in-roof panels, there are usually 12-20 solar panels in one group. If the productivity of one of these panels decreases (shadows from trees and clouds, dust, bird droppings, failures of PV components and other factors), then the productivity of the whole group decreases. Defective or shaded panels may produce 15 to 25 percent less solar energy ...

What is a Power Conditioner?

Image
  Looking to protect your sensitive and expensive electronics? Surge protection is a great start, but power conditioners also offer valuable protection for components in entertainment and sound systems, as well as home office devices. What does a power conditioner do that a surge protector can’t? Surge protectors are a great defense against damaging voltage spikes. However more than surges and spikes can effect certain sensitive electronic devices. Radio frequency interference (RFI), electro-magnetic interference (EMI) and voltage fluctuations can also effect sound, entertainment, and office devices, causing a reduction in sound and picture quality. How does it work? Power conditioners act as a buffer between the outlet and your system, smoothing out voltage fluctuations as well as radio and electromagnetic interference that can effect system performance. Initially used in industrial, research and laboratory applications, not long after the introduction of home computer systems, th...
