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 closed- loop bandwidth even when the transimpedance is about several tens of k Ω 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.

Exposure to any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime. (2) The inputs are protected by ESD protection diodes to the power supply. If the input extends more than 300 mV beyond the power supply, the input current should be limited to less than 10 mA. (3) A heat sink may be required to keep the junction temperature below the absolute maximum rating. This depends on the power dissipation of the application. Thermal resistance varies with the amount of PC board metal connected to the package.
