STMicroelectronics (ST) has launched its TSZ181H1 and dual TSZ182H1 automotive-qualified operational amplifiers (op amps) for automotive and industrial applications. These devices deliver high accuracy and stability over a wide -40°C to 175°C temperature range for use in harsh environments.

The op amps also deliver a very low input offset voltage, typical 3.5 µV at 25°Cm, and input bias current, typical 30 pA at 25°C. ST said the parameters display minimal drift over temperature, with maximum input offset voltage specified as 70 µV at 25°C and 100 µV over the full temperature range. The maximum specified input bias current is 200 pA at 25°C and 225 pA over the full range.
In addition to withstanding harsh environments thanks to their wide operating-temperature range, the TSZ181H1 and TSZ182H1 also can operate for an extended lifetime in applications that require a long mission profile. The devices are AEC-Q100 qualified and provide 4-kV HBM ESD tolerance.
The new op amps can be used for precision signal conditioning without calibration, said ST, which helps simplify end-product manufacturing while providing higher accuracy.
Other specs include a gain bandwidth of 3 MHz, an operating current of just 1 mA at 5 V and a power supply voltage range from 2.2 V to 5.5 V. Both devices have rail-to-rail input and output to maximize usable dynamic range, said ST.
Both op amps are in production and available in SOT23-5 or SO8 packages. Pricing starts at $1.58 for the TSZ181H1 and $2.66 for the TSZ182H1 dual op amp.
