STMicroelectronics’ flexible new op amp ideal for automotive and industrial applications

The STMicroelectronics‘ TSB622 general-purpose, low-power, dual-operational amplifier (op amp) enhances ruggedness and flexibility in industrial and automotive applications.

The unity-gain stable TSB622 operates over the extended temperature range (between -40° to 125° C) and is automotive-qualified. The broad supply-voltage range, from 2.7 to 36V, lets designers use the same device for multiple applications with different voltage domains.

The rail-to-rail output maximizes dynamic range while the input offset voltage of 1mV ensures competitive precision for a low-power device.

With a gain-bandwidth (GBW) product of 1.7MHz and a maximum operating current of 375μA per channel (at 36V supply), the TSB622 delivers high speed relative to power consumption. The low supply current allows use in applications that demand low-power operation and extends the runtime of battery-operated equipment.

In addition, 4kV ESD tolerance (HBM – human-body model) and enhanced resistance to electromagnetic interference ensure the TSB622 withstands the technically demanding industrial and automotive environments.

The TSB622 dual op-amp is now packaged in SO8 and MiniSO8 styles that save board space and can help reduce the overall cost of the PCB. Available by July, the 3mm x 3mm DFN8 package will come with wettable flanks that provide extra mechanical strength to meet the automotive industry requirements.
