MODULE CIRCUIT 11.0504B OPERATION - DESCRIPTION

The control element is the operational NE5534. This is a very low noise operational, especially designed

for very high quality applications in professional audio equipment, control equipment and telephony channel
amplifiers.

The operational is internally compensated for a gain equal to or higher than three. Frequency response

can be optimized with an external compensation capacity, for several applications (unity gain amplifier, capacitive
load, slew-rate, low overshoot, etc...).

Output drive capability: 600

POWER SUPPLY

The BF871 and BF872 transistors are mounted in a common

base configuration, in a current source structure. The current sources
have a double function: polarizing the gate-source links in the MOSFETs
to the limit of the conduction and moving the voltage variations at the
operational output which are refered to ground to voltage variations
refered to high voltage power supply. The polarization point is calculated
so the voltage dropout in Rc(R112+R111) is the limit voltage of
conduction of the MOSFETs (

.

2 to 3V), enough to carry the bias

current. If we modulate in AC the base-emitter voltage, the Ic and VRc
will vary proportionally. In our configuration, as the reference voltage Vref
is constant (it is a part of the operational power supply), we add the
operational output voltage to the transistors emitter through Re
(R107-R108).

The Rc value fixes the source output impedance. We do not

recommend to raise it higher than 1K

Ω

because of frequency response

and slew rate reasons. This voltage circuit's gain is, as usual in a
common base configuration with Rc/Re emitter resistor, 0.45.
