PBL38812 Overview
Description
The PBL 388 12 contains all the necessary circuitry, amplifiers, detectors, comparators and control functions to implement a high performance, voice-switched, ”hands-free ” function in an answering machine. The gain dynamics (attenuation between channels) is settable (25dB or 50dB) via CTR pin that also control two mute levels.
Key Features
- Settable gain dynamics (25 or 50 dB)
- Low power consumption, totally 1.0mA at 3.3V typical
- Background noise compensation in the transmitting channel with hold function
- Exellent noise performance
- Both channel input amplifiers have balanced inputs
- Minimum of external components needed for function
