Low voltage PLL stereo decoder TDA7040T
GENERAL DESCRIPTION
The TDA7040T is a monolithic integrated circuit for low cost FM stereo radios with an absolute minimum of peripheral
components and a simple lay-out.
Features
• Built-in four pole low pass filter with a 70 kHz corner frequency suppressing unwanted out-of-band input signals
• Fully integrated 228 kHz oscillator
• Pilot presence detector and soft mono/stereo blend
• Built-in interference suppression
• External stereo lamp driver applicable
• Adjustable gain.
