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
