TDA3810
DESCRIPTION
The TDA3810 integrated circuit provides spatial, stereo and pseudo-stereo sound for radio and television equipment.
Features
Three switched functions:
spatial (widened stereo image)
stereo
pseudo-stereo (artificial stereo from a mono source)
Offset compensated operational amplifiers to reduce switch noise
LED driver outputs to facilitate indication of selected operating mode
Start/stop circuit to reduce switch noise and to prevent LED-flicker
TTL-compatible control inputs
