The TSZ182 dual-precision op amp from STMicroelectronics combines low and temperature-stable input-offset voltage with the added advantages of a 3 MHz gain-bandwidth, rail-to-rail inputs and outputs, and ultrasmall 2 x 2 mm DFN8 or Mini-SO8 package options. Complementing ST’s conventional op amps, the chopper-stabilised version enables precision in instruments like body-signal monitors, blood-glucose meters, industrial sensors, factory automation and low-side current sensing.

The offset voltage of 25 µV at 25°C enables high-measurement resolution without external trimming components, saving board space and the need for adjustments during production. Offset drift of less than 100 nV/°C maintains accuracy over a wide temperature range and saves periodic auto-recalibration, thereby simplifying design and enhancing convenience for end users.

Operating from a 2.2–5.5 V supply and providing rail-to-rail inputs and outputs, the product maximises use of the available dynamic range. The gain-bandwidth of 3 MHz ensures consistent frequency response over a wide range, while the maximum operating current of just 1 mA at 5 V helps maximise runtime of battery-powered devices.

The extended operating temperature range of -40 to 125°C enables use in harsh outdoor or industrial environments. Automotive-qualified variants (TSZ1821IYST) will offer precision sensor-signal conditioning in equipment ranging from simple wiper modules or climate controls to autonomous driving systems.
