DescriptionThe TDA8926TH is the switching power stage of a two-chip set for a high efficiency class-D audio power amplifier system.With this chip set a compact 2 ´ 50 W audio amplifier system can be built, operating with high efficiency and very low dissipation. No heatsink is required, or depending on supply voltage and load, a very small one. The system operates over a wide supply voltage range from±15 up to ±30 V and consumes a very low quiescent current.
The TDA8926TH has many unique features: The first one is high efficiency (>94%).The second one is operating voltage from ±15 to ±30 V.The third one is very low quiescent current.The forth one is high output power.The fifth one is diagnostic output.The sixth one is usable as a stereo Single-Ended (SE) amplifier or as a mono amplifier in Bridge-Tied Load (BTL).The seventh one is standby mode.The eighth one is electrostatic discharge protection (pin to pin),etc.
There are some limiting values about the TDA8926TH.storage temperature(Tstg) is -55°C +150°C.Ambient temperature(Tj) is -40°C to 85°C.supply voltage(VP) is ±30 V max.supply voltage for short-circuits across the load(VP(sc)) is ±30 V max.repetitive peak current in output pins(IORM) is 5 A max.virtual junction temperature(Tvj) is 150 °C max.thermal resistance from junction to ambient in free air(Rth(j-a))is 40 K/W.thermal resistance from junction to case in free air(Rth(j-c)) is 1 K/W.
Well,if you are interested in the TDA8926TH and want to know more,please pay more attention to our web for you will find more information about it. Thanks for your attention!
The TDA8926TH is the switching power stage of a two-chip set for a high efficiency class-D audio power amplifier system. The system is split into two chips:
` TDA8926TH: a digital power stage in a HSOP24 power package
` TDA8929T: the analog controller chip in a SO24 package.
With this TDA8926TH set a compact 2 * 50 W audio amplifier system can be built, operating with high efficiency and very low dissipation. No heatsink is required, or depending on supply voltage and load, a very small one. The system operates over a wide supply voltage range from ±15 up to ±30 V and consumes a very low quiescent current.
