TDF8599 I2C-bus controlled dual channel 43 W/2 Ω single channel 85 W/1 Ω class-D power amplifier with load diagnostics Rev. 01 — 13 November 2008 Product data sheet 1. General description The TDF8599 is a dual Bridge-Tied Load (BTL) car audio amplifier comprising an NDMOST-NDMOST output stage based on SOI BCDMOS technology. Low dissipation enables the TDF8599 high-efficiency, class-D amplifier to be used with a smaller heat sink than those normally used with standard class-AB amplifiers. www.DataShe.

TDF8599 I2C-bus controlled dual channel 43 W/2 Ω single channel 85 W/1 Ω class-D power amplifier with load diagnostics Rev. 01 — 13 November 2008 Product data sheet 1. General description The TDF8599 is a dual Bridge-Tied Load (BTL) car audio amplifier comprising an NDMOST-NDMOST output stage based on SOI BCDMOS technology. Low dissipation enables the TDF8599 high-efficiency, class-D amplifier to be used with a smaller heat sink than those normally used with standard class-AB amplifiers. www.DataSheet4U.com The TDF8599 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 five I2C-bus addresses can be selected when an external resistor is connected to pin ADS. When pin ADS is short circuited to ground, the TDF8599 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. 2.
