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 Ω resistor and
additional two resistors (58 Ω and 98 Ω) on the hybrid allow
adjustment of the transducer bias current of the receiver.
