FEATURES
DESCRIPTION

HIGH BANDWIDTH: 500 MHz (G = +2 V/V)
The OPA653 combines a very wideband
voltage-feedback operational amplifier with a
HIGH SLEW RATE: 2675 V/μs (4-V Step)
JFET-input stage with internal gain setting resistors to
EXCELLENT THD: –71dBc at 10 MHz
achieve an ultra-high, dynamic-range amplifier for
LOW INPUT VOLTAGE NOISE: 6.1 nV/Hz
fixed gain of +2-V/V or –1-V/V applications.
FAST OVERDRIVE RECOVERY: 8 ns
The 500-MHz wide gain of +2-V/V bandwidth is
FAST SETTLING TIME (1% 4-V Step): 7.9 ns
complemented by a very high 2675-V/μs slew rate
and fast settling time that make it ideal for
LOW INPUT OFFSET VOLTAGE: ±1 mV
time-domain and pulse-oriented applications.
LOW INPUT BIAS CURRENT: ±10 pA
Excellent –72-dBc THD distortion performance at
HIGH INPUT IMPEDANCE: 10
12
||2.5 pF
10 MHz makes the OPA653 an excellent choice for
INTERNAL GAIN SETTING RESISTORS:
frequency-domain and FFT analysis applications.
G = +2 V/V or G = –1 V/V
Additionally, with the low 6.1-nV/Hz voltage noise,
HIGH OUTPUT CURRENT: 70 mA
low bias current, and high impedance JFET input, it
supports very low noise, wideband, high input
APPLICATIONS
impedance applications. Examples include
TEST AND MEASUREMENT FRONT-END
high-impedance probes, data acquisition cards, and
HIGH-INPUT IMPEDANCE PROBES
oscilloscope front-ends.
