The THS4631 is a high-speed, FET-input op amp designed for applications requiring wideband operation, high-input impedance, and high-power supply voltages. By providing a 210MHz gain bandwidth product, ±15V supply operation, and 100pA input bias current, the THS4631 is capable of simultaneous wideband transimpedance gain and large output signal swing. The fast 1000V/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.

These high-performance characteristics make the THS4631 an excellent choice for use as a wideband photodiode amplifier. Photodiode output current is a prime candidate for transimpedance amplification. Other potential applications include test and measurement systems requiring high-input impedance, ADC and DAC buffering, high-speed integration, and active filtering.

The THS4631 is offered in a 8-pin SOIC (D) package, and 8-pin HSOIC (DDA) and HVSSOP (DGN) with PowerPAD™ integrated-circuit packages.
