Low Power Op Amp

TSZ121 family: Ultra precision and low-power op amp for IoT applications

ST’s new zero-drift op amps ideal choice for sensor and control interfaces in a wide range of battery-powered IoT applications.

The devices operate from 1.8V to 5.5V, with quiescent current below 40μA at 5V, gain-bandwidth product of 400kHz, and ultra-low input bias current.

  • The single-channel TSZ121 is pin- and package-compatible with comparable devices from other manufacturers.
  • The dual-channel TSZ122 offers popular MiniSO-8 and SO-8 packages plus the option of a miniature 2mm x 2mm DFN8.
  • The TSZ124 quad op amp in TSSOP-14 and 3mm x 3mm QFN16

This family provides the industry’s broadest choice of zero-drift op amps.

Op-amps for CO detector

Unmonitored gas can rapidly become a danger. Consequently, monitoring air quality is mandatory for security reasons in many industries.

ST's op amps TSU101 nanopower amplifier, TV711TSV731 high precision op amps and TSZ121 chopper amplifier  take into account bias voltage and polarity variations and help ensure the best sensitivity in 2- and 3-electrode gas sensors.

Moreover, their low supply voltage and ultra-low power consumption, while delivering almost no current, make them a perfect fit for handheld safety detectors operating in toxic environments.
