DESCRIPTION
The OPA655 combines a very wideband, unity gain
stable, voltage feedback op amp with a FET input
stage to offer an ultra high dynamic range amplifier
for ADC buffering and transimpedance applications.
Extremely low harmonic distortion along with excel-
lent pulse settling characteristics will support even the
most demanding ADC input buffer requirements.
The broad unity gain stable bandwidth and FET input
allows exceptional performance in high speed, low
noise integrators.
The high input impedance and low bias current pro-
vided by the FET input is further supported by the
ultra-low 6nV/
√
Hz input voltage noise to achieve a
very low integrated noise in wideband photodiode
transimpedance applications.
Broad transimpedance bandwidths are achievable given
the OPA655’s high 240MHz gain bandwidth product.
As shown below, a –3dB bandwidth of 1MHz is
provided even for a high 1M
transimpedance gain
from a 47pF source capacitance.
