TDF8599CTH/N1,118

TDF8599CTH/N1,118 is a I2C-bus controlled stereo class-D amplifier 136W/8ohm with full diagnostics. This 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. The TDF8599C 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 15 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 TDF8599C 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. Applications include car audio and audio entertainment systems.
