PBL38570規(guī)格書詳情
Description.
PBL 38570 is a monolithic integrated speech transmission circuit for use in electronic telephones. It is designed to accomodate either a low impedance dynamic or an electret microphone. A separate input for DTMF dialling tones that is controlled by a mute signal, and a signal summing point at the transmitter input, are available.
Key features.
? Minimum number of external components, 7 capacitors and 11 resistors.
? Easy adaption to various market needs.
? Mute control input for operation with DTMF - generator.
? A separate input for DTMF tones controlled by mute.
? Transmitter and receiver gain regulation for automatic loop loss compensation.
? Extended current and voltage range 5 - 130 mA, down to 2 V.
? Differential microphone input for good balance to ground.
? Balanced receiver output stage.
? Stabilized DC - supplies for low current CMOS diallers and electret microphones.
? 18 - pin DIP and 20 - pin SO packages.
? Short start up time.
? Excellent RFI performance.
