Low-Power Dual Operational Amplifier

STMicroelectronics has introduced the new general-purpose low-power dual operational amplifier TSB622 that enhances ruggedness and flexibility in industrial and automotive applications and features a broad supply-voltage range from 2.7V to 36V which lets designers use the same device for multiple applications with different voltage domains. This automotive-qualified amplifier operates over the extended temperature range -40°C to 125°C and 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), this device 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.
