OPA2380AIDGKT

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

The OPA2380AIDGKT 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 amplifier 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 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.
