GENERAL DESCRIPTION
The TDA8571J is a integrated class-B output amplifier
contained in a 23-lead Single-In-Line (SIL) plastic power
package. It contains four amplifiers in a BTL configuration,
each with a gain of 34 dB. The output power is 4

(EIAJ) into a 4
Ω
load.
APPLICATIONS
•
Primarily developed for car radio applications.
