STMicroelectronics has set out to target the industrial and automotive analog circuit markets by introducing the 'TSB192' dual operational amplifier, which simultaneously secures a wide operating voltage range and high precision.

On the 27th, STMicroelectronics unveiled a new operational amplifier operating from 4V to 36V and stated that it simultaneously supports the signal processing accuracy and stability required in various electronic applications.

The newly announced TSB192 features a low offset voltage of 20µV and a temperature drift of 100nV/°C. Unlike products with similar precision that are typically limited to low-voltage environments, this product is designed to operate stably even at relatively high voltages. Another feature is that it maintains the offset voltage at a constant level across the entire temperature range, thereby reducing reliance on separate compensation circuits.

In terms of power efficiency, it is designed with a maximum current consumption of 1.9mA per channel, which can extend the usage time of battery-based equipment. In addition, the range of signal utilization was expanded by applying a rail-to-rail output structure.

This product can be applied to analog circuits in various measurement and control systems, such as temperature sensors, medical equipment, electronic scales, and industrial test equipment. Its 8 MHz gain bandwidth, 5 V/μs slew rate, and low input noise characteristics contribute to reducing signal distortion and improving frequency response performance in transducer or strain gauge-based systems.

The operating temperature range is set from -40°C to 125°C, allowing for use in automotive environments, and it features electrostatic discharge (ESD) resistance up to 4kV. The product is supplied in SO-8 and MiniSO-8 packages, and the automotive-grade product is scheduled for release in the second half of 2026.
