资 源 简 介
The THS4631 is a high-speed, FET-input operaTIonal amplifier designed for applicaTIons requiring wideband operaTIon, high-input impedance, and high-power supply voltages. By providing a 210-MHz gain bandwidth product, ±15-V supply operaTIon, and 100-pA input bias current, the THS4631 is capable of simultaneous wideband transimpedance gain and large output signal swing. The fast 1000 V/µs slew rate allows for fast settling times and good harmonic distortion at high frequencies. Low current and voltage noise allow amplification of extremely low-level input signals while still maintaining a large signal-to-noise ratio.
The characteristics of the THS4631 make it ideally suited for use as a wideband photodiode amplifier.
