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 of GS551 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 GS551 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.
