Datasheet

- production data

Features

 Multipower BCD technology

 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

 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

– Capable to operate down to 6 V (e.g.

“Startstop”)

Description

The STPA001 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.

The STPA001 can operate down to 6 V and this

makes the IC compliant to the most recent OEM

specifications for low voltage operation (so called

'start-stop' battery profile during engine stop),

helping car manufacturers to reduce the overall

emissions and thus contributing to environment

protection.
