GM3008
FEATURES
- up to 80 d B of electrical gain
- dedicated preamp for a telecoil
- direct coupling of a telecoil to preamp
- low input referred noise
- on chip voltage regulator
- capable of driving low impedance receivers
DESCRIPTION
The GM3008 hybrid consists of two of Gennum's proprietary integrated circuits, the GP537 preamplifier and the GS551 class B output driver. Such a configuration provides up to 80 d B (typ) of electrical gain. Low total harmonic distortion and input noise make this circuit well suited for high power applications. Various additional pads have been provided to allow for maximum flexibility of system performance. The GP537 contains two low noise inverting preamplifiers with an open loop voltage gain of typically 50 d B, a telecoil preamplifier with its own reference voltage which enables for direct coupling of the telecoil and a voltage regulator with typically 74 d B of supply rejection capable of working with a supply voltage down to 1.1 volts.
