ML1490
RF/IF/Audio Amplifier
Wideband Amplifier With AGC
Legacy Device: Motorola MC1490
The ML1490 is an integrated circuit featuring
wide–range AGC for use in RF/IF amplifiers and audio
amplifiers.
• 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
• Operating Temperature Range TA = –40° to +85°C
Note: See Similar ML1350 For Possible Option
MAXIMUM RATINGS (TA = +25°C, unless otherwise noted.)
