AF105 Datasheet | National Semiconductor

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 - Od Bm output level - Internal reference - Wide supply voltage range - Input level range - Frequency range ±9.0 V to ±18 V +30d Bm (2.45Vrms) 500 Hz to 10 k Hz Connection Diagram LOOP TC2 - - V- GAIN DC INPUT DIVIDER INT RECii VEiiv LOOP OUTPUT CDMM (+) TCl Ceramic Dual- ln-line Package HY24A AF104CJ AF105CJ - Internally connected.
