GENERAL DESCRIPTION

The TDA1554Q is an integrated class-B output amplifier in a 17-lead single-in-line (SIL) plastic power package.

The circuit contains 4 x 11 W single-ended or 2 x 22 W bridge amplifiers. The device is primarily developed for car radio applications.

Features
∙	Requires very few external components	∙	Thermally protected
∙	Flexibility in use − Quad single-ended or stereo BTL	∙	Reverse polarity safe
∙	High output power	∙	Capability to handle high energy on outputs (VP = 0 V)
∙	Low offset voltage at outputs (important for BTL)	∙	Protected against electrostatic discharge
∙	Fixed gain	∙	No switch-on/switch-off plop
∙	Good ripple rejection	∙	Low thermal resistance
∙	Mute/stand-by switch	∙	Identical inputs (inverting and non-inverting)
∙	Load dump protection	∙	Flexible leads.
∙	AC and DC short-circuit-safe to ground and VP

FUNCTIONAL DESCRIPTION

The TDA1554Q contains four identical amplifiers with differential input stages (two inverting and two non-inverting) and can be used for single-ended or bridge applications. The gain of each amplifier is fixed at 20 dB (26 dB in BTL). A special feature of this device is:

Mute/stand-by switch

·low stand-by current (< 100 mA)

·low mute/stand-by switching current (low cost supply switch)

·mute facility
