DESCRIPTION
The LP508 is an 8 pin Class A amplifier utilizing Gennum's
proprietary low voltage bipolar JFET technology. It consists of
2 single ended, low noise inverting gain blocks. The first block
has a typical open loop gain of 50 dB, with the closed loop gain
set by the ratio of the feedback resistor to the the source
impedance. The second block has the output transistor bias
set by
R
E
and
V
RE at pin 7 which is 27 mV.
Typically, the gain of the first block is set to 29 dB, with the
second block at 32 dB, giving a total gain of 61 dB.
