The THS4601 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 180-MHz gain-bandwidth product, ±15-V supply operation, and 100-pA input bias current, the THS4601 is capable of wideband transimpedance gain and large output signal swing simultaneously. 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 THS4601 ideally suit it for use as a wideband photodiode amplifier. Photodiode output current is a prime candidate for transimpedance amplification, an application of which is illustrated in Figure 1. Other potential applications include test and measurement systems requiring high-input impedance, digital-to-analog converter output buffering, high-speed integration, and active filtering.
