FEATURES  
DESCRIPTION  
2
HIGH BANDWIDTH: 500 MHz (G = +2 V/V)  
HIGH SLEW RATE: 2675 V/µs (4-V Step)  
EXCELLENT THD: –71dBc at 10 MHz  
LOW INPUT VOLTAGE NOISE: 6.1 nV/Hz  
FAST OVERDRIVE RECOVERY: 8 ns  
FAST SETTLING TIME (1% 4-V Step): 7.9 ns  
LOW INPUT OFFSET VOLTAGE: ±1 mV  
LOW INPUT BIAS CURRENT: ±10 pA  
HIGH INPUT IMPEDANCE: 1012 ||2.5 pF  
The OPA653 combines  
voltage-feedback operational amplifier with  
a
very  
wideband  
a
JFET-input stage with internal gain setting resistors to  
achieve an ultra-high, dynamic-range amplifier for  
fixed gain of +2-V/V or –1-V/V applications.  
The 500-MHz wide gain of +2-V/V bandwidth is  
complemented by a very high 2675-V/µs slew rate  
and fast settling time that make it ideal for  
time-domain and pulse-oriented applications.  
Excellent –72-dBc THD distortion performance at  
10 MHz makes the OPA653 an excellent choice for  
frequency-domain and FFT analysis applications.  
INTERNAL GAIN SETTING RESISTORS:  
G = +2 V/V or G = –1 V/V  
Additionally, with the low 6.1-nV/Hz voltage noise,  
low bias current, and high impedance JFET input, it  
supports very low noise, wideband, high input  
HIGH OUTPUT CURRENT: 70 mA  
APPLICATIONS  
impedance  
applications.  
Examples  
include  
TEST AND MEASUREMENT FRONT-END  
HIGH-INPUT IMPEDANCE PROBES  
DATA ACQUISITION CARDS  
OSCILLOSCOPE INPUT  
high-impedance probes, data acquisition cards, and  
oscilloscope front-ends.
