DESCRIPTION
The OPA686 combines very high gain bandwidth and large
signal performance with very low input voltage noise while
dissipating a low 12mA supply current. The classical differen-
tial input stage, along with two stages of forward gain and a
high power output stage, combine to make the OPA686 an
exceptionally low distortion amplifier with excellent DC accu-
racy and output drive. The voltage feedback architecture allows
all standard op amp applications to be implemented with very
high performance.
The combination of low input voltage and current noise, along
with a 1.6GHz gain bandwidth product, make the OPA686 an
ideal amplifier for wideband transimpedance stages. As a volt-
age gain stage, the OPA686 is optimized for a flat response at a
gain of +10 and is guaranteed stable down to a noise gain of +7.
High Gain, 20MHz Transimpedance Amplifier
TM
A new external compensation technique can be used to give a
very flat frequency response below the minimum stable gain
for the OPA686, further improving its already exceptional
distortion performance. Using this compensation makes the
OPA686 one of the premier 12- to 14-bit analog-to-digital
converter input drivers. The supply current for the OPA686 is
precisely trimmed to 12.4mA at +25
°
C. This, along with
carefully defined supply current tempcos in the input and
output stages, combine to provide exceptional performance
over the full specified temperature range.
