In the ever-evolving landscape of analogue building blocks, STMicroelectronics breaks new ground with the introduction of the TSB182 dual op-amp. This automotive-rated op amp stands out by seamlessly blending medium-voltage operation and precision performance, addressing the unique demands of high-accuracy automotive and industrial signal conditioning with sensors.
The TSB182, packaged in a compact MiniSO-8 format (approximately 3 × 3 mm), caters to designers seeking a harmonious combination of performance attributes. With an operating voltage range spanning from 4 to 36 V, this op-amp excels in precision with a maximum input offset voltage of 30 µV over the full temperature range (20 µV @ 25°C) and a 100 nV/°C drift over temperature.
What sets the TSB182 apart is its ability to merge fast dynamic response and low power consumption, boasting a mere 650 μA typical operating current per amplifier. The gain-bandwidth product (GBW) is an impressive 3 MHz, accompanied by a slew rate of 2 V/µs, ensuring minimal output distortion across the frequency spectrum. The op amp’s input noise voltage of 24 nV/√Hz caters to applications demanding high resolution and front-end signal sensitivity.
Beyond its performance attributes, the TSB182 is designed to endure challenging environments. It is hardened against electromagnetic interference, enhancing performance in electrically noisy settings. Additionally, it offers a robust electrostatic-discharge tolerance of 4 kV HBM (human body model).
Precision analogue-circuit designers can access comprehensive details in the 30-page datasheet, featuring tables, charts, and graphs characterizing all aspects of performance at both nominal and extended settings. The TSB182 is specified for operation from −40 to 125°C, with AEC-Q100-qualified devices also available. Priced at $0.96 (1,000 pieces) in the MiniSO-8 package, STMicroelectronics plans to introduce a standard SO-8 package option later in the year, with automotive-qualified device pricing starting at $1.15. This innovative dual op amp from STMicroelectronics redefines possibilities in precision signal conditioning for automotive applications.
