TDA8594J中文资料I2C-bus controlled 4 x 50 W power amplifier数据手册恩XP规格书
TDA8594J规格书详情
描述 Description
The TDA8594 is a complementary quad Bridge Tied Load (BTL) audio power amplifier made in BCDMOS technology. It contains four independent amplifiers in BTL configuration. Through the I²C-bus, diagnosis of temperature warning and clipping level is fully programmable and the information available via two diagnostic pins is selectable. The status of each amplifier (output offset, load or no load, short-circuit or speaker incorrectly connected) can be read separately.
特性 Features
General
• Operates in legacy mode (non I²C-bus) and I²C-bus mode (3.3 V and 5 V compliant)
• Three hardware-programmable I²C-bus addresses
• Drives 4 Ω or 2 Ω loads
• Speaker fault detection
• Independent short-circuit protection per channel
• Loss of ground and open VP safe (with 200 mΩ series impedance and a supply decoupling capacitor of 2200 μF maximum)
• All outputs short-circuit proof to ground, supply voltage and across the load
• All pins short-circuit proof to ground
• Temperature-controlled gain reduction to prevent audio holes at high junction temperatures
• Low battery voltage detection
• Offset detection
• This part has been qualified in accordance with AEC-Q100
I²C-bus mode
• DC load detection: open-circuit, short-circuit and load present
• AC load (tweeter) detection
• During start-up, can detect which load is connected so the appropriate gain can be selected without audio pop
• Independently selectable soft mute of front channels (channel 1 and channel 3) and rear channels (channel 2 and channel 4)
• Programmable gain (26 dB and 16 dB) of front channels (channel 1 and channel 3) and rear channels (channel 2 and channel 4)
• Fully programmable diagnostic levels can be set:
• Programmable clip detection: 2 %, 5 % or 10 %
• Programmable thermal pre-warning
• Selectable information on the DIAG and STB pins:
• The STB pin can be programmed/multiplexed with second clip detection
• Clip information of each channel can be directed separately to the DIAG pin or the STB pin
• Independent enabling of thermal, clip or load fault detection (short across or to VP or to ground) on DIAG pin
