THS4601

SLOS388B – OCTOBER 2001 – REVISED JUNE 2002

WIDEBAND, FET-INPUT OPERATIONAL AMPLIFIER

FEATURES

DESCRIPTION

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.
