GENERAL DESCRIPTION
The TDA9845 is a stereo/dual sound processor for TV and VTR sets. Its identification ensures safe operation by using internal digital PLL technique with extremely small bandwidth, synchronous detection and digital integration (switching time maximum 2.1 s; identification concerning the main functions).

FEATURES
• Supply voltage 5 to 8 V
• Source selector
• Stereo matrix
• AF input for mono source
• AF outputs for Main
• LED operation mode indication (stereo and dual)
• High identification reliability.
