Product Overview


The OPA381AIDGKT is a precision low-power high-speed Transimpedance Amplifier provides extremely high precision, excellent long-term stability and very low 1/f noise. The OPA381 features an offset voltage, offset drift and bias current. The OPA381 far exceeds the offset, drift and noise performance that conventional JFET operational amplifier provide. The signal bandwidth of a transimpedance amplifier depends largely on the GBW of the amplifier and the parasitic capacitance of the photodiode, as well as the feedback resistor. The 18MHz GBW of the OPA381 enables a trans-impedance bandwidth in most configurations. The OPA381 is ideally suited for fast control loops for power level measurement on an optical fibre.
  • 250kHz Transimpedance bandwidth

  • 10nV/√Hz Low voltage noise
  • 3pA Bias current
  • 25µv Maximum offset voltage
  • 0.1µV/°C Maximum offset drift
  • Fast overload recovery
  • 2.7 to 5.5V Supply range
  • Green product and no Sb/Br
