single op ampnanopowerrail-to-rail I/OCMOSSOT-23-5sensor conditioning

TP2121-TR is a single nanopower rail-to-rail CMOS op amp for low-frequency, battery-operated sensing and signal-conditioning circuits.

Best for

  • Ultra-low-power sensor conditioning
  • Battery current sensing
  • High-impedance sensor buffering
  • Low-frequency threshold detection

Avoid if

  • Fast signal amplification is required
  • Wide closed-loop bandwidth is required
  • A specified lifecycle status is mandatory

Check before use

  • Verify gain and bandwidth margin
  • Evaluate offset error in the complete signal chain
  • Validate stability with the actual capacitive load
  • Confirm output swing and load-current requirements
