STMicroelectronics Introduces New Automotive Qualified Operational Amplifiers

STMicroelectronics' TSZ181H1 and dual TSZ182H1 automotive-qualified operational amplifiers (Op Amplifiers) offer high accuracy and stability over a wide temperature range (-40° to 175° C). High maximum operating temperature encourages use in harsh environments and in applications with long mission profiles.

Operational amplifiers have very low input offset voltage, typically 3.5 µV at 25°Cm, and input bias current, typically 30 pA at 25°C. Maximum input offset specified as 70 µV at 25°C. and 100 µV across the entire temperature range. The specified maximum input bias current is 200pA at 25°C and 225pA over the entire range.

With their wide operating temperature range, the TSZ181H1 and TSZ182H1 withstand harsh environments in industrial and automotive applications. At lower die temperatures, they can operate for an extended lifetime in applications that require ICs with a long mission profile. The devices are AEC-Q100 qualified and have an ESD HBM tolerance of 4kV.

The TSZ181H1 and TSZ182H1 provide excellent performance in high-precision, high-bandwidth sensor interfaces. They can be used for precision signal conditioning without calibration, thereby simplifying final product manufacturing and ensuring greater accuracy than typical operational amplifiers. The 3 MHz gain bandwidth and operating current of just 1 mA at 5 V provide a superior speed-to-power ratio.

Designed for a wide supply voltage range, from 2.2 to 5.5 V, both devices feature rail-to-rail input and output to maximize usable dynamic range.
