The TSZ182 dual op-amp is a 5V chopper-stabilized op amp with a 3MHz gain bandwidth, rail-to-rail inputs and outputs, and ultra-small 2 x 2mm DFN8 or Mini-SO8 packages. The offset voltage of 25µV at 25°C enables high measurement resolution and precision.
These features make the TSZ182 ideal for high-accuracy high-bandwidth sensor interfaces like body-signal monitors, blood-glucose meters, industrial sensors, factory automation, automotive applications and low-side current sensing.
The extended operating temperature range of -40 to 125°C enables use in harsh outdoor or industrial environments. Automotive qualified variants (TSZ182IYST) are also available for precision sensor signal conditioning in equipment ranging from simple wiper modules or climate controls to autonomous driving systems.
This chopper represent today the smallest package (DFN8 2x2mm) offer as for as high accuracy (virtually unaffected by temperature changes) and high bandwidth needs. Specifically the TSZ182 shows the widest VCC range from 2.2V up to 5.5V with the lowest low supply voltage (2.2V).
With rail-to-rail input/ output and 3MHz gain bandwidth product, the TSZ182 offers excellent speed/power consumption ratio, while consuming just 1mA at 5V. The device also features an ultra-low input bias current. It is ideal for high accuracy high-bandwidth sensor interfaces.
