STMicroelectronics TSB622 high-voltage op amp

Click2Contact

STMicroelectronics’ TSB622 general-purpose, low-power dual operational amplifier (op amp) is designed to enhance ruggedness and flexibility in industrial and automotive applications.

The unity-gain stable device operates over an extended temperature range, -40 to 125°C, and is automotive-qualified. The broad supply-voltage range, from 2.7 to 36 V, lets designers use the same device for multiple applications with different voltage domains. The rail-to-rail output maximises dynamic range, while the input offset voltage of 1 mV offers precision for a low-power device.

With a gain-bandwidth (GBW) product of 1.7 MHz and maximum operating current of 375 μA per channel (at 36 V supply), the op amp 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, 4 kV ESD tolerance (HBM — human-body model) and enhanced resistance to electromagnetic interference mean the product withstands the technically demanding industrial and automotive environments.

The 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. The 3 x 3 mm DFN8 package will come with wettable flanks that provide extra mechanical strength to meet the automotive–industry requirements.
