GS551 DATA SHEET
FEATURES
CIRCUIT DESCRIPTION
• adjustable gain to 48 dB
• capable of driving low impedance receiver
The GS551 is a 10 pin, low voltage, class B amplifier which
operates over a battery range of 1.1 VDC to 3 VDC.
• low component count, 3 small capacitors and 1 resistor
• gain trim can be used as vol. control for reduced noise
• minimal start-up transient
• no gain expansion
STANDARD PACKAGING
• 10 pin MICROpac
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.
• 10 pin PLID®
• 10 pin SLT
• Chip (68 x 60 mils)
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.
