Key Features

  • Quad op-amp architecture with four independent amplifiers in a single SO-14 package, saving board space
  • Ultra-low input bias current of 0.00006 µA enables high-impedance sensor interfacing
  • 80 dB typical common-mode rejection ratio ensures accurate signal amplification in noisy environments
  • Single-supply operation optimized for 3.3 V and 5 V systems in portable and battery-powered designs
  • Voltage-feedback architecture with frequency compensation for stable closed-loop performance

Applications

The TLC274CDR is widely used in sensor signal conditioning circuits where high input impedance and low bias current are essential, such as pH probes, strain gauges, and photodiode amplifiers. Its quad package and single-supply compatibility make it a popular choice for active filter designs, data acquisition front-ends, and portable instrumentation. The device also suits audio processing, precision voltage references, and industrial control applications requiring low-power quad op-amp solutions.
