BLOCK DIAGRAM
DESCRIPTION
The LX509 consists of 4 independent low noise, low current
inverting operational amplifiers utilizing Gennum's low voltage
bipolar JFET technology. Each amplifier has a minimum open
loop gain of 46 dB with the closed loop gain set by the ratio of
a feedback (R
F) resistor to the source impedance (RS) .
For
a well controlled gain tolerance from amplifier to amplifier, it is
recommended that the closed loop gain is at least 20 dB below
the open loop gain.
Three of the preamplifiers, A, C and D are capable of delivering
typically 30
A of peak current drive while the fourth pre-
amplifier B has 6 dB more current drive capability, allowing a
6 dB greater output into the same load impedance, or the same
output level into one half the load impedance.
