Wideband, Fixed Gain, JFET-Input AMPLIFIER

FEATURES

DESCRIPTION

•

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: 10¹²Ω||2.5 pF

The OPA653 combines

voltage-feedback operational amplifier with

very

wideband

•

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
