The OPA380AIDG4 is a high speed precision Transimpedance Amplifier provides high-speed (90MHz gain bandwidth (GBW)) operation, with extremely high precision, excellent long-term stability and very low 1/f noise. It is ideally suited for high-speed photodiode applications. The OPA380 features an offset voltage of 25µV, offset drift of 0.1µV/°C and bias current of 50pA. The OPA380 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 90MHz GBW of the OPA380 enables a transimpedance bandwidth of >,1MHz in most configurations. The OPA380 is ideally suited for fast control loops for power level on an optical fibre.
