Stmicroelectronics Flexible high voltage operational amplifier targeted for automotive and industrial applications

     Stmicroelectronics TSB622 General low power bioperator amplifier (op amp) for enhanced robustness and flexibility in industrial and automotive applications. The TSB622 has a stable unit gain, the operating temperature range extends to -40°C to 125°C, and has obtained the vehicle gauge class certification. It supports a wide supply voltage ranging from 2.7V to 36V. Designers can use the same device to design a variety of applications with different voltage domains, and the track-to-rail output maximizes the dynamic range. At the same time, the 1mV input offset voltage ensures that the low power amplifier also has high accuracy.

     The unit gain of the TSB622 is stable, and the operating temperature range is expanded to - 40 ° C to 125 ° C. The TSB622 has obtained the vehicle specification level certification, and supports a wide power supply voltage of 2.7V to 36V. Designers can use the same device to design multiple applications with different voltage domains. Rail to rail output maximizes the dynamic range. At the same time, 1mV input offset voltage ensures that the low power op amp also has high accuracy.

     Gain bandwidth product (GBW) is 1.7MHz, and the maximum working current of each channel is 375 μ A (at 36V power supply), the TSB622 achieves a high speed to power ratio. The power supply current is small, suitable for low power consumption applications, and helps to extend the running time of battery powered equipment.

     In addition, the 4kV ESD withstand voltage (HBM - manikin) and enhanced anti electromagnetic interference capability ensure that TSB622 can withstand the industrial and automotive environments with stringent technical requirements. TSB622 dual op amp is now packaged with SO8 and MiniSO8, which can save circuit board space and help reduce the overall cost of PCB. The 3mm x 3mm DFN8 package launched in July will be equipped with a wettable flaps structure, which can provide additional mechanical strength to meet the requirements of the automotive industry.
