DESCRIPTION
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.
