AUDIO AMPLIFIER. TBA810S Datasheet
LINEAR INTEGRATED CIRCUIT
1 W AUDIO AMPLIFIER
The TBA 810 S is a monolithic integrated circuit in a 12 lead quad in-line plastic package, intended for
use as a low frequency class B amplifier.
The TBA 810 S provides 7 W power output at 16 V/4 n, 6 W at 14.4 V/If n, 2.5 W at9 V/4 n, 1 Wat
6 V/4 n and works with a wide range of supply voltages (4 to 20 V); it gives high output current (up to
2.5 A), high efficiency (75% at 6 W output). very low harmonic and cross-over distortion. In addition,
the circuit is provided with a thermal protection circuit.
The TBA 810 AS has the same electrical characteristics as the TBA 810S, but its cooling tabs are flat
and pierced so that an external heatsink can easily be attached.
