SBOS251E – JULY 2002 – REVISED DECEMBER 2008  
Wideband, Ultra-Low Noise, Voltage-Feedback  
OPERATIONAL AMPLIFIER with Shutdown  
DESCRIPTION  
FEATURES  
The OPA847 combines very high gain bandwidth and large  
signal performance with an ultra-low input noise voltage  
(0.85nV/√Hz) while using only 18mA supply current. Where  
power saving is critical, the OPA847 also includes an op-  
tional power shutdown pin that, when pulled low, disables the  
amplifier and decreases the supply current to < 1% of the  
powered-up value. This optional feature may be left discon-  
nected to ensure normal amplifier operation when no power-  
down is required.  
● HIGH GAIN BANDWIDTH: 3.9GHz  
● LOW INPUT VOLTAGE NOISE: 0.85nV/  
√Hz  
● VERY LOW DISTORTION: –105dBc (5MHz)  
● HIGH SLEW RATE: 950V/µs  
● HIGH DC ACCURACY: VIO < ±100µV  
● LOW SUPPLY CURRENT: 18.1mA  
● LOW SHUTDOWN POWER: 2mW  
● STABLE FOR GAINS ≥ 12  
The combination of very low input voltage and current noise,  
along with a 3.9GHz gain bandwidth product, make the  
OPA847 an ideal amplifier for wideband transimpedance  
applications. As a voltage gain stage, the OPA847 is opti-  
mized for a flat frequency response at a gain of +20V/V and  
is stable down to gains as low as +12V/V. New external  
compensation techniques allow the OPA847 to be used at  
any inverting gain with excellent frequency response control.  
Using this technique in a differential Analog-to-Digital Con-  
verter (ADC) interface application, shown below, can deliver  
one of the highest dynamic-range interfaces available.  
APPLICATIONS  
● HIGH DYNAMIC RANGE ADC PREAMPS  
● LOW NOISE, WIDEBAND, TRANSIMPEDANCE  
AMPLIFIERS  
● WIDEBAND, HIGH GAIN AMPLIFIERS  
● LOW NOISE DIFFERENTIAL RECEIVERS  
● ULTRASOUND CHANNEL AMPLIFIERS  
● IMPROVED UPGRADE FOR THE OPA687,  
CLC425, AND LMH6624
