STMicroelectronics (hereinafter ST) announced on the 14th that it has released the TSB622, a general-purpose low-power dual operational amplifier (Op Amp) that enhances the robustness and flexibility of industrial and automotive applications.

Featuring stable unity gain, the TSB622 operates over an extended temperature range of -40°C to 125°C and has achieved automotive quality grade. It also offers a wide supply voltage range of 2.7V to 36V, allowing designers to use the same device for various applications with different voltage domains. It was explained that while the rail-to-rail output maximizes dynamic range, an input offset voltage of 1mV ensures excellent precision in low-power devices.

ST stated that the TSB622 offers fast speed relative to power consumption, featuring a gain bandwidth (GBW) of 1.7 MHz and a maximum operating current of 375 μA per channel (based on a 36 V supply voltage). The low supply current is suitable for applications requiring low-power operation and can extend the runtime of battery-powered equipment.

It was also added that it is effective in technically demanding industrial and automotive environments through a 4kV ESD tolerance (HBM: Human-Body Model) and enhanced immunity to electromagnetic interference.

The TSB622 dual operational amplifier is also available in SO8 and MiniSO8 packages, which save board space and reduce overall PCB costs. The DFN8 package, available in 3mm x 3mm from July, also supports a Wettable Flank package that further enhances mechanical strength, meeting automotive industry requirements.
