Description

The TPH2861 is a high-speed, low-noise operational

amplifier with high-speed BJT inputs, suitable for

broadband cross resistance and voltage amplifier

applications.

The device with 8-GHz GBP can achieve enough closedloop

bandwidth even when the transimpedance is about

several tens of kΩ in the wideband trans-impedance (TIA)

applications.

The TPH2861 also has a large-signal bandwidth of 850

MHz (2 VPP) , a slew rate of 2750 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.
