GENERAL DESCRIPTION
TDA1556Q is a monolithic integrated class-B output
amplifier containing two 22 Watt amplifiers in a BTL
configuration. The device is contained in a 17-lead
single-in-line (SIL) plastic power package. It has two
differential inputs and is primarily intended for car booster
applications.
