STMicroelectronics’ TSB622 low-power dual operational amplifier improves ruggedness and flexibility in industrial and automotive applications.

STMicroelectronics’ TSB622 low-power dual operational amplifier improves ruggedness and flexibility in industrial and automotive applications.

The stable unity gain TSB622 operates over the extended temperature range, -40°C to 125°C, and is automotive qualified. The wide supply voltage range, from 2.7 V to 36 V, allows designers to use the same device for multiple applications with different voltage ranges. The rail-to-rail output maximizes dynamic range while the 1mV input offset voltage ensures competitive accuracy for a low-power device.

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

Additionally, 4kV ESD tolerance (HBM – human body model) and increased resistance to electromagnetic interference ensure that the TSB622 withstands technically demanding industrial and automotive environments.

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