GS3010 Hybrid
with LS509 Amplifier
GS3010 - HYB DATA SHEET
FEATURES
鈥?Gennum鈥檚 LS509 3 stage amplifier
鈥?independent preamp can be used as telecoil
preamplifier
鈥?four 鈥渕ust use鈥?capacitors mounted on hybrid
鈥?choice of 3 resistors to set transducer current
鈥?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
鈩?/div>
resistor and
additional two resistors (58
鈩?/div>
and 98
鈩?
on the hybrid allow
adjustment of the transducer bias current of the receiver.
