STMicroelectronics TSB182 dual operational amplifier

STMicroelectronics’ TSB182 dual operational amplifier is designed for high-accuracy signal conditioning with sensors, including maximum 20 µV input offset voltage, 100 nV/°C drift over temperature and 4–36 V operating range for medium-voltage applications.

In addition to its wide supply-voltage range, the dual operational amplifier is specified from -40 to 125°C. With maximum offset voltage of 30 µV over the full temperature range, the op amps provide consistent performance in industrial and automotive environments. The package options include MiniSO-8, which helps designers save board space and target smaller module sizes. AEC-Q100 qualified devices are also available.

The dual operational amplifier also combines fast dynamic response and low power consumption, with typical operating current of 650 μA per amplifier. The gain-bandwidth product (GBW) is 3 MHz, with slew rate of 2 V/µs, for minimal output distortion across the frequency range. The input noise voltage of 24 nV/√Hz fulfils applications that require high resolution and sensitivity. The devices are also hardened against electromagnetic interference for enhanced performance in electrically noisy environments. Having rail-to-rail outputs, the dual operational amplifier helps designers utilise the available signal dynamic range and ease circuit design in applications including sensor interfaces and battery-powered equipment.

The TSB182 is in production and available now in MiniSO-8. ST will add a standard SO-8 option later in the year.
