3PEAK – Operationsverstärker mit geringem Stromverbrauch

Operationsverstärker mit geringem Stromverbrauch

Let's take a closer look at the low-power operational amplifiers from the manufacturer 3PEAK. The portfolio includes amplifiers with quiescent current in the nano-ampere range and low bandwidth in the kilohertz range up to amplifiers with bandwidths in the megahertz range and quiescent current in the micro-ampere range.

The 3PEAK portfolio offers solutions for various applications with different power consumption requirements. From sensor interfaces, filters, motor controllers, white goods and medical applications to battery-powered mobile and portable devices as well as applications using energy harvesting.

Application example with TP211x

The TP211x can be used for signal amplification of oxygen sensors. An exemplary schematic can be found in the diagram on the right. For the version with one channel (TP2111), 2 versions are available - with and without shut-down pin. In shut-down mode, the TP2111N typically consumes only 3nA typical and its output is switched to high impedance.

The operating temperature range of -40°C to +125°C enables use in many different applications, even if high temperatures occur close to a sensor due to the process environment.
