TDA3825
GENERAL DESCRIPTION
The TDA3825 is a single FM demodulator system with external AF input and mute.
Features
• Supply voltage range from 4.5 V to 13.2 V
• AC coupled AF stage
• Multiple input AF operational amplifier with offset compensation
• External AF input
• High AF output voltage with low distortion
• AF gain of 0 dB without external components
• Frequency response can be determined by external components
• High ripple rejection
• Low switching noise between AF and mute
