ST introduces TSZ182 precision dual operational amplifier

ST introduces the TSZ182 precision dual op amp, which features low input offset voltage and high temperature drift stability, as well as 3MHz gain bandwidth, rail-to-rail input and output, 2mm x 2mm DFN8 or Mini-SO8 micro package. Advantage.

The TSZ182 chopper-stabilized op amp further complements ST's well-received traditional op amp product line, allowing the instrument to be extremely accurate, suitable for body signal monitors, blood glucose meters, industrial sensors, factory automation and low Side current measurement.

The new operation has an offset voltage of 25μV at 25°C, which enables high measurement resolution and accuracy without the need for external trimming devices, saving board space and eliminating the need for tuning on the production line. In addition, the input offset temperature drift remains within 100nV/°C over a wide temperature range, eliminating the need for a periodic automatic calibration process, which simplifies product design and provides greater convenience for end users.

Rail-to-rail input and output make the new product more competitive than other brands of precision op amps, operating power supply voltage 2.2V-5.5V, these two advantages allow the TSZ182 to take full advantage of the existing dynamic range. The 3MHz gain bandwidth ensures that the frequency response remains stable over a wide range. A maximum operating current of 1 mA at 5V helps maximize the battery life of battery-powered equipment.
