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. the 500-mhz wide gain of +2-v/v bandwidth is complemented by a very high 2675-v/s 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. additionally with the low 6.1-nv/vhz voltage noise low bias current and high impedance jfet input it supports very low noise wideband high input impedance applications. view all in datasheet
