Description of Application Circuit
1. Preamplifier
The preamplifier circuit consists of the input differential stage (TR9, 10), level shift stage (TR13), and output stage
(TR17, 18, 19). Since the output stage is of push-pull type, no remarkable drop in the output voltage occurs even at
low load impedances and the output can be connected direct to the ALC circuit and meter circuit. The external
DC/AC feedback resistor (Z2) can be set arbitrarily and the closed loop gain is obtained by the following equation.
Z2
VG (pre) 20 log (Z1) (dB)
The input impedance depends on internal resistance R2 which is 30kΩ.
