GENERAL DESCRIPTION
is the next generation
performance, and lower noise and power consumption. It is an
ideal choice for driving high performance ADCs as a single-ended-
to-differential or differential-to-differential amplifier. The output
common-mode voltage is user adjustable by means of an internal
common-mode feedback loop, allowing the
ideal choice for driving high performance ADCs as a single-ended-
to-differential or differential-to-differential amplifier. The output
common-mode voltage is user adjustable by means of an internal
common-mode feedback loop, allowing the
output
to match the input of the ADC. The internal feedback loop also
provides exceptional output balance as well as suppression of
even-order harmonic distortion products.
With the
provides exceptional output balance as well as suppression of
even-order harmonic distortion products.
With the
, differential gain configurations are easily
realized with a simple external four-resistor feedback network that
determines the closed-loop gain of the amplifier.
The
determines the closed-loop gain of the amplifier.
The
is fabricated using the Analog Devices, Inc.,
proprietary silicon-germanium (SiGe) complementary bipolar
process, enabling it to achieve low levels of distortion and noise
at low power consumption. The low offset and excellent dynamic
performance of the
process, enabling it to achieve low levels of distortion and noise
at low power consumption. The low offset and excellent dynamic
performance of the
make it well suited for a wide
variety of data acquisition and signal processing applications.
