NXP Semiconductors announced enhancements to its family of Class-AB audio amplifiers, providing improved quiescent current reduction and decreased smartphone signal interference. The integrated GSM input filtering is built in for increased EMC robustness. The TDF8546A (4 x 25 Watt) and TDF8548A (4 x 28 Watt) also extend line driver detection to 1 kΩ load impedance.
Designed specifically for automotive applications, the devices provide increased GSM robustness to mitigate the influence of smartphones on loud speakers, responding to OEMs’ demand for a cost-effective solution that improves sound quality.
The amplifiers are available with NXP’s ‘Best Efficiency Mode’ operating as low as 6 V, for a claimed 17% reduction in power dissipation compared to other high-efficiency solutions in its class. Both amplifiers enable a seamless audio experience during sudden supply voltage drops in hybrid electric vehicles and other cars using start-stop systems.
The ICs feature no switch noise thanks to soft switching, and are protected against short thermal overload and electrostatic discharge. They incorporate I2C bus diagnostics, including startup diagnostics, clip detection and pre-warning. They are supplied in HSOP36 and DBS27 packages.
