FEA TURES HIGH BANDWIDTH: 400MHz (G = +10) LOW INPUT VOLTAGE NOISE: 1.2nV/√Hz VERY LOW DISTORTION: –100dBc (5MHz) HIGH SLEW RATE: 625V/μs HIGH DC ACCURACY: VIO ±150μV LOW SUPPLY CURRENT: 12.6mA HIGH GAIN BANDWIDTH PRODUCT: 1750MHz STABLE FOR GAINS ≥ 7
DESCRIPTIONThe OPA846 combines very high gain bandwidth and large
signal performance with very low input voltage noise, while
dissipating a low 12.6mA supply current. The classical differ-
ential input stage, along with two stages of forward gain and
a high power output stage, combine to make the OPA846 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 1.75GHz gain bandwidth product, make the
OPA846 an ideal amplifier for wideband transimpedance
stages. As a voltage gain stage, the OPA846 is optimized for
a flat response at a gain of +10 and is stable down to a gain
of +7.
High Gain, 20MHz Transimpedance AmplifierA new external compensation technique can be used to give
a very flat frequency response below the minimum stable
gain for the OPA846, further improving its already excep-
tional distortion performance. Using this compensation makes
the OPA846 one of the premier 12- to 16-bit Analog-to-Digital
(A/D) converter input drivers. The supply current for the
OPA846 is precisely trimmed to 12.6mA at +25°C. This,
along with carefully defined supply current tempco in the
input and output stages, combine to provide exceptional
performance over the full specified temperature range.
