A6 53 www.ti.com SBOS348A – DECEMBER 2008 – REVISED NOVEMBER 2009 Wideband, Fixed Gain, JFET-Input AMPLIFIER
Check for Samples: OPA653 FEATURES DESCRIPTION The OPA653 combines a very wideband
voltage-feedback operational amplifier with 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. 1 23 HIGH BANDWIDTH: 500 MHz (G = +2 V/V)
HIGH SLEW RATE: 2675 V/Ојs (4-V Step)
EXCELLENT THD: –71dBc at 10 MHz
LOW INPUT VOLTAGE NOISE: 6.1 nV/в€љHz
FAST OVERDRIVE RECOVERY: 8 ns
FAST SETTLING TIME (1% 4-V Step): 7.9 ns
LOW INPUT OFFSET VOLTAGE: В±1 mV
LOW INPUT BIAS CURRENT: В±10 pA
HIGH INPUT IMPEDANCE: 1012 Ω||2.5 pF
INTERNAL GAIN SETTING RESISTORS:
G = +2 V/V or G = –1 V/V
HIGH OUTPUT CURRENT: 70 mA APPLICATIONS TEST AND MEASUREMENT FRONT-END
