PBL388131SO規(guī)格書(shū)詳情
Description.
The PBL 388 13 contains all the necessary circuitry, amplifiers, detectors, comparator and control functions to implement a high performance, voice-switched, loudspeaking, ”hands-free ” telephone. The gain dynamics (attenuation between channels) is selectable (25dB or 50dB) via a separate pin. A background noise detector in the transmitting channel reduces the influence of continuous external noise signals to the switching .
Key Features
? Minimum of external components needed for function.
? Selectable gain dynamics. (25 or 50 dB)
? Direct telephone line powered solution (patented).
? Low power consumption:≈1mA at 3.3V (typical) for speech switching, audio power amplifier quiscent current ≈1mA.
? Drives an 25 - 50 ohm loudspeaker without a transformer.
? Background noise compensation in the transmitting channel with hold function at receive.
? Input amplifiers of both channels have balanced inputs.
? Exellent noise performance.
? Encapsulated in 24 pin plastic ”skinny” DIP and 24 pin SO .
