OPA859 Datasheet (Texas Instruments)

OPA859, FET Input Amplifier

The OPA859 is a wideband, low-noise operational amplifier with CMOS inputs for wideband transimpedance and voltage amplifier applications.

When the device is configured as a transimpedance amplifier (TIA), the 0.9-GHz gain bandwidth product (GBWP) enables high closed-loop bandwidths in lowcapacitanc
