TDF8599C 2 I C-bus controlled stereo class-D amplifier 136 W/8 with full diagnostics Rev. 1 5 August 2011 Product short data sheet 1. General description The TDF8599C is a dual Bridge-Tied Load (BTL) car audio amplifier comprising an NDMOST-NDMOST output stage based on SOI BCDMOS technology. Low power dissipation enables the TDF8599C high-efficiency, class-D amplifier to be used with a smaller heat sink than those normally used with standard class-AB amplifiers. 2 2 The TDF8599C can operate in either non-I C-bus mode or I C-bus mode. When in 2 I C-bus mode, DC load detection results and fault conditions can be easily read back from 2 the device. Up to 15 I C-bus addresses can be selected depending on the value of the external resistors connected to pins ADS and MOD. 2 When pin ADS is short circuited to ground, the TDF8599C operates in non-I C-bus mode. 2 Switching between Operating mode and Mute mode in non-I C-bus mode is only possible using pins EN and SEL MUTE. 2.
