Description
STPA008 is a breakthrough MOSFET technology class AB audio power amplifier designed for high power car radio. The fully complementary P-Channel/N-Channel output structure allows a rail to rail output voltage swing which, combined with high output current and minimized saturation losses sets new power references in the car-radio field, with unparalleled distortion performances.
Features
• High output power capability:
– 4 x 50 W/4 Ω Max.
– 4 x 28 W/4 Ω @ 14.4 V, 1 kHz, 10 %
– 4 x 72 W/2 Ω Max.
• MOSFET output power stage
• 2 Ω driving capability
• Capable to operate down to 6 V (suitable for
start-stop car operation)
• Excellent GSM noise immunity
• Hi-Fi class distortion
• Low output noise
• High immunity to RF noise injection
• Standby function
• Mute function
• Automute at min. supply voltage detection
• Low external component count
• Internally fixed gain (26 dB)
• Protections:
– Output short circuit to GND, to Vs, across
the load
– Very inductive loads
– Overrating chip temperature with soft
thermal limiter
– Output DC offset detection
– Load dump
– Fortuitous open GND
– Reversed battery
– ESD
• Qualification in accordance to AEC Q100
standard
