MC1490
RF/IF/Audio Amplifier
The MC1490 is an integrated circuit featuring wide–range AGC for use in
RF/IF amplifiers and audio amplifiers over the temperature range, –40° to
+85°C.
• High Power Gain: 50 dB Typ at 10 MHz
45 dB Typ at 60 MHz
35 dB Typ at 100 MHz
• Wide Range AGC: 60 dB Min, DC to 60 MHz
• 6.0 V to 15 V Operation, Single Polarity Supply
• See MC1350D for Surface Mount
