Supports Multiple Output Configurations
and Short Circuit With Error Reporting
–
2×20-W into a 8-
BTL Load at 18 V
–
4×10-W into a 4-
SE Load at 18 V
–
2×10W (SE) + 1×20W (BTL) at 18 V
Flat-Panel, Rear-Projection, and CRT TV
Thermally Enhanced Package
–
DCA (56-pin HTTSOP)
Wide Voltage Range: 10V–26V
The TAS5601 is a 20-W (per channel) efficient,
stereo digital amplifier power stage for driving 4
–
No Separate Supply Required for Gate
single-ended speakers, 2 bridge-tied speakers, or
Drive
combination of single and bridge-tied loads. The
Efficient Class-D Operation Eliminates Need
TAS5601 can drive a speaker with an impedance as
for Heat Sinks
low as 4
. The high efficiency, >90% into 8- loads,
Closed Loop Power Stage Architecture
of the TAS5601 eliminates the need for an external
heat sink.
–
Improved PSRR Reduces Power Supply
Performance Requirements
A simple interface to a digital audio PWM processor
is shown below. The TAS5601 is fully protected
–
High Damping Factor Provides for Tighter,
against faults with short-circuit protection and thermal
More Accurate Sound With Improved Bass
protection as well as overvoltage and undervoltage
Response
protection. Faults are reported back to the processor
–
Constant Output Power Over Variation in
to prevent devices from being damaged during
Supply Voltage
overload conditions.
