FEATURES DESCRIPTION The TPA31xxD2 series are stereo efficient, digital • Supports Multiple Output Configurations 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 high efficiency 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 layer PCB. The TPA3118D2 can (TPA3118D2) even run 2x30W/8Ω without heat sink on a dual layer PCB. If even higher power is needed the TPA3116D2 – 2×15-W into a 8-Ω BTL Load at 15 V does 2x50W/4Ω with a small heat-sink attached to its (TPA3130D2) top side PowerPad. All three devices share the same • Wide Voltage Range: 4.5 V – 26 V footprint enabling a single PCB to be used across • Efficient Class-D Operation different power levels. – >90% Power Efficiency Combined with Low The TPA31xxD2 advanced oscillator/PLL circuit Idle Loss Greatly Reduces Heat Sink Size employs a multiple switching frequency option to – Advanced Modulation Schemes avoid AM interferences; this is achieved together with an option of Master/Slave option, making it possible • Multiple Switching Frequencies to synchronize multiple devices. – AM Avoidance The TPA31xxD2 devices are fully protected against – Master/Slave Synchronization faults with short-circuit protection and thermal – Up to 1.2 MHz Switching Frequency protection as well as over-voltage, under-voltage and • Feedback Power Stage Architecture with High DC protection. Faults are reported back to the processor to prevent devices from being damaged PSRR Reduces PSU Requirements during overload conditions. • Programmable Power Limit • Differential/Single-Ended Inputs Simplified Application Circuit • Stereo and Mono Mode with Single Filter Mono Configuration • Single Power Supply Reduces Component Count • Integrated Self-Protection Circuits Including Over-Voltage, Under-Voltage, OverTemperature, 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 Pad down (DAP) TPA3116D2 2 x 50W/4Ω Pad up (DAD) APPLICATIONS • Mini-Micro Component, Speaker Bar, Docks • After-Market Automotive • CRT TV • Consumer Audio Applications
