Frequently Asked Questions
What is the recommended working voltage range for the TEA0679T?
The device operates with power supplies from 7.6 to 12 V.
How does the IC handle music pauses during Automatic Music Search (AMS)?
It detects pauses and allows equalization with an electronically switched time constant microcontroller reaction, or can detect pauses in "AMS latch mode" for simple tape drivers.
What input controls are available on this dual noise reduction circuit?
Level adjustment, output offset adjustment, and all switching functions are controlled via I^2C-bus; optional switch inputs are TTL compatible.
What package type is used for the TEA0679T?
It is contained in a 32-pin small outline package (SO32).
