Description
TDF8599B I2C-bus controlled dual channel 43 W/4 Ω, single channel 85 W/1 Ω class-D power amplifier with load diagnostics Rev. 01 — 29 July 2009 Product data sheet 1. General description The TDF8599B 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 TDF8599B 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 TDF8599B 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 resistor connected to pins ADS and MOD. When pin ADS is short circuited to ground, the TDF8599B 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.
