| GS3010 Hybrid with LS509 Amplifier GS3010 - HYB DATA SHEET FEATURES * Gennum's LS509 3 stage amplifier * independent preamp can be used as telecoil preamplifier * four "must use" capacitors mounted on hybrid * choice of 3 resistors to set transducer current * easy assembly and high reliability DESCRIPTION The hybrid consists of an LS509 amplifier, four capacitors, and two selectable bias resistors. The values of the capacitors assure proper operation of the circuit for the most commonly required frequency responses. If a different frequency response is required, external components can be easily connected to the additional solder pads connected to various amplifier access points. The jumper connection of the on-chip 125 resistor and additional two resistors (58 and 98 ) on the hybrid allow adjustment of the transducer bias current of the receiver.
