DESCRIPTION
T
he GS563 is a low noise, low current, inverting amplifier which
utilizes Gennum's low voltage bipolar JFET technology.
The amplifier has a minimum open loop gain of 45 dB with the
closed loop gain set by the ratio of feedback resistor to the
input resistor. For a well controlled gain tolerance, it is
recommended that the closed loop gain be at least 20 dB
below the open loop gain.
The device is internally bias compensated, preventing any DC
current flow via external feedback resistors. It is ideally suited
for filtering applications and can be used as a drop in
replacement for single transistor configurations.
