Операционные усилители OPA380AIDGKT

Трансимпедансный усилитель , 5.5 В, 90 МГц, 7.5 мА, 9.5 мА, 400 мВ, MSOP

The OPA380AIDGKT is a precision high-speed 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 op-amps 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. As a result of the high precision and low-noise characteristics of the OPA380, a dynamic range of 4 to 5 decades can be achieved.
