2 x 22 W BTL car radio power amplifier
with diagnostic facility
Preliminary specification
TDA1551Q
FEATURES
• Requires very few external components
• Flexible in use - quad, single ended or stereo BTL
• I²C-bus control
• Dynamic distortion detector
• Thermal protection
• Output status information
• Power supply dip detection
• High output power
• MUTE/sleep mode by writing to I²C-bus
• Stand-by mode
• Fixed gain
• Good ripple rejection
• Load dump protection
• AC/DC short circuit safe to ground and V_P
• Reverse polarity safe
• Low offset voltage at output
• Capable of handling high energy at outputs (V_P = 0 V)
• Electrostatic discharge protection
• No switch-ON/switch-OFF plop
• Flexible leads
• Low thermal resistance
• Identical inputs (inverting and non-inverting).
DESCRIPTION
The TDA1551Q is an integrated class-B output amplifier
encased in a 17-lead single-in-line plastic power package.
The device contains 4 × 11 W single-ended (SE) or 2 × 22
W BTL amplifiers and is intended for use in car radio
applications.
