CIRCUIT DESCRIPTION
The GS551 is a 10 pin, low voltage, class B amplifier which
operates over a battery range of 1.1 VDC to 3 VDC.
The GS551 consists of three gain blocks. The first block is
an inverting amplifier with the gain set by two external
resistors. The gain trim feature can be used as a volume
control in hearing aid applications. The second block is an
inverting unity gain amplifier which serves as a phase
splitter. The outputs from the first and second blocks drive
the differential input of the third block. The third block has
a fixed AC gain of 28 dB when driving a receiver.
The amplifier has internal compensation eliminating the
need for a capacitor across the receiver. Two ground pins
are available for “Star” grounding to reduce any second
order harmonic distortion introduced by ground line resistance.
