Class-AB (car radio)
Confirmed by outstanding customer feedback, NXP Class-AB amplifiers have best-in-class audiophile sound performance. They include a full range of diagnostics, which increase quality and enable reduced costs. Due to low voltage operation (6 V), Class-AB amplifiers support start-stop capabilities, and in best efficiency mode you can achieve low power dissipation and high output power.
NXP is the leader for sound performance in Class-AB amplifiers for car radio and sound systems. A key feature of this quality is low DC offset voltage, which avoids pop noise. And for general purpose noise reduction the amplifiers are offered with differential inputs.
The Class-AB amplifier output stages are suitable for 2 Ohm to 4 Ohm speakers. But the latest generation of these amplifiers is ideal for stop/start automotive applications, operable as low as 6V while offering high power output.
The amplifier is controlled by I²;C bus and legacy mode can be used to diagnose clip detection and provide a high temperature warning at around 122 -145 C. These audio Class-AB power amplifiers are ideal for car radio head units, available in small foot print packages (HSOP36 or DBS27) with different bending for horizontal use.
