Description for the OPA653
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/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.
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 impedance applications. Examples include high-impedance probes, data acquisition cards, and oscilloscope front-ends.
