The TDF8530 is a quad Bridge-Tied Load (BTL) car audio amplifier comprising an NDMOST-NDMOST output stage based on SOI BCDMOS technology. Low power dissipation enables the TDF8530 high-efficiency, class-D amplifier to be used with a smaller heat sink than those normally used with standard class-AB amplifiers.

The TDF8530 can operate in either non-I²C-bus mode or I²C-bus mode. When in I²C-bus mode, DC load detection results and fault conditions can be easily read back from the device. Up to 12 I²C-bus addresses can be selected depending on the value of the external resistors connected to pins ADS and MOD.

When pin ADS is short circuited to ground, the TDF8530 operates in non-I²C-bus mode. Switching between Operating mode and Mute mode in non-I²C-bus mode is only possible using pins EN and SEL_MUTE.
