2
× 22 W stereo BTL car radio power amplifier with
loudspeaker protection and 3-state mode switch
TDA1553CQ
DC CHARACTERISTICS
VP = 14.4 V; Tamb =25 °C; measured in Fig.4; unless otherwise specified.
Notes
1. The circuit is DC adjusted at VP = 6 to 18 V and AC operating at VP =9to18V.
2. If any output is short-circuited to ground during the standby mode and in this condition the circuit is switched to mute
or operating condition.
3. At 18 V
< VP < 30 V the DC output voltage ≤VP/2.
