Gain Bandwidth Product: 180 MHz  
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.  
Slew Rate: 100 V/µs  
Maximum Input Bias Current: 100 pA  
Input Voltage Noise: 5.4 nV/√Hz  
Maximum Input Offset Voltage: 4 mV

Input Impedance: 10 Ω || 10 pF  
Power Supply Voltage Range: ±5 to ±15 V  
Unity Gain Stable  
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  
measurementsystemsrequiringhigh-inputimpedance,  
digital-to-analog converter output buffering, high-speed  
integration, and active filtering.
