AF104/AF105 DTMF AGe Amplifier
General Description
The AF104 AGC Amplifier is a direct coupled amplifier whose voltage gain is internally controlled by the output
signal.
The gain control feedback system is AC coupled so that DC signals do not affect the gain.
Features
- Optional gain adjustment - High input impedance
100k
- OdBm output level - Internal reference - Wide supply voltage range - Input level range - Frequency range
±9.
0 V to ±18 V +30dBm (2.
45Vrms)
500 Hz to 10 kHz
