OPA657  
OPA657  
SBOS197B – DECEMBER 2001 – REVISED MAY 2004  
1.6GHz, Low-Noise, FET-Input  
OPERATIONAL AMPLIFIER  
FEATURES  
DESCRIPTION  
The OPA657 combines a high gain bandwidth, low distor-tion,  
voltage-feedback op amp with a low voltage noise JFET-input  
stage to offer a very high dynamic range amplifier for high  
precision ADC (Analog-to-Digital Converter) driving or wideband  
transimpedance applications. Photodiode applications will see  
improved noise and bandwidth using this decompensated,  
high gain bandwidth amplifier.  
HIGH GAIN BANDWIDTH PRODUCT: 1.6GHz  
HIGH BANDWIDTH 275MHz (G = +10)  
LOW INPUT OFFSET VOLTAGE: ±0.25mV  
LOW INPUT BIAS CURRENT: 2pA  
LOW INPUT VOLTAGE NOISE: 4.8nV/ Hz  
HIGH OUTPUT CURRENT: 70mA  
Very low level signals can be significantly amplified in a single  
OPA657 gain stage with exceptional bandwidth and accuracy.  
Having a high 1.6GHz gain bandwidth product will give >  
10MHz signal bandwidths up to gains of 160V/V (44dB). The  
very low input bias current and capacitance will support this  
performance even for relatively high source impedances.  
FAST OVERDRIVE RECOVERY  
APPLICATIONS  
WIDEBAND PHOTODIODE AMPLIFIER  
WAFER SCANNING EQUIPMENT  
ADC INPUT AMPLIFIER  
Broadband photodetector applications will benefit from the low  
voltage noise JFET inputs for the OPA657. The JFET input  
contributes virtually no current noise while for broadband  
applications, a low voltage noise is also required. The low  
4.8nV/ Hz input voltage noise will provide exceptional input  
sensitivity for higher bandwidth applications. The example  
shown below will give a total equivalent input noise current of  
1.8pA/ Hz over a 10MHz bandwidth.
