TDA3810

sound circuit

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
