AF104 Datasheet - DTMF AGC Amplifier

II) ~ ~National ~ ~ Semiconductor o u~. 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 Connection Diagram LOOP TC2 24 * *V- GAIN DC INPUT DIVIDER INT RECiiVEiiv LOOP OUTPUT CDMM (+) TCl Ceramic Dual·ln-line Package HY24A AF104CJ AF105CJ *Internally connected.
