TPA3118D2DAPR的详细描述：

    FEATURES DESCRIPTION
• Supports Multiple Output Configurations The TPA31xxD2 series arestereo efficient, digital
amplifier power stage for driving speakers up to
– 2×50-W into a 4-Ω BTL Load at 21 V 100W/2Ω in mono. The highefficiency of the
(TPA3116D2) TPA3130D2 allows it to do 2x15W without external
– 2×30-W into a 8-Ω BTL Load at 24 V heat sink on a single layerPCB. The TPA3118D2 can
(TPA3118D2) even run 2x30W/8Ω without heat sink on a duallayer
– 2×15-W into a 8-Ω BTL Load at 15 V PCB. If even higher power isneeded the TPA3116D2
(TPA3130D2) does 2x50W/4Ω with a small heat-sink attached toits
top side PowerPad. All three devices share the same
• Wide Voltage Range: 4.5 V – 26 V footprint enabling a single PCBto be used across
• Efficient Class-D Operation different power levels.
– >90% Power Efficiency Combined with Low The TPA31xxD2 advancedoscillator/PLL circuit
Idle Loss Greatly Reduces Heat Sink Size employs a multipleswitching frequency option to
– Advanced Modulation Schemes avoid AM interferences; this isachieved together with
an option of Master/Slave option, making it possible • MultipleSwitching Frequencies to synchronize multiple devices.
– AM Avoidance
The TPA31xxD2 devices are fully protected against
– Master/Slave Synchronization faults with short-circuit protectionand thermal
– Up to 1.2 MHz Switching Frequency protection as well asover-voltage, under-voltage and
• Feedback Power Stage Architecture with High DC protection. Faultsare reported back to the
PSRR Reduces PSU Requirements processor to prevent devices frombeing damaged
during overload conditions.
• Programmable Power Limit
• Differential/Single-Ended Inputs Simplified ApplicationCircuit
• Stereo and Mono Mode with Single Filter Mono
Configuration
• Single Power Supply Reduces Component
Count
• Integrated Self-Protection Circuits Including
Over-Voltage, Under-Voltage, Over-
Temperature, DC-Detect, and Short Circuit
with Error Reporting
• Thermally Enhanced Packages
– DAD (32-pin HTSSOP Pad-up) DEVICE POWER HTSSOP 32-PIN
– DAP (32-pin HTSSOP Pad-down) TPA3130D2 2 x 15W/8Ω Pad down(DAP)
• –40°C to 85°C Ambient Temperature Range TPA3118D2 2 x 30W/8Ω Paddown (DAP)
TPA3116D2 2 x 50W/4Ω Pad up (DAD)
