TPH2861 High-Speed Op Amp

3PEAK high-speed, low-noise operational amplifier includes high-speed BJT inputs

Image of 3PEAK TPH2861 High-speed Op Amp3PEAK TPH2861 is a high-speed, low-noise operational amplifier with high-speed BJT inputs that is suitable for broadband cross-resistance and voltage amplifier applications. The device has a 8 GHz GBP that can achieve closed-loop bandwidth even when the transimpedance is about several tens of kΩ in wideband trans-impedance (TIA) applications.

The TPH2861 has a large-signal bandwidth of 850 MHz (2 VPP), a slew rate of 2,750 V/μs, and only 2.8 ns for overload recovery, making it suitable for high-speed pulse applications. The feedback pin (FB) of the TPH2861 decreases the distance of the feedback network connection between the input and output on the PCB, which benefits the achievement of high closed-loop bandwidth.
