The high efficiency of the TPA3130D2 allows it to do 2x15W without external heat sink on a single layer PCB. The TPA3118D2 can even run 2x30W/80 without heat sink on a dual layer PCB. If even higher power is needed the TPA3116D2 does 2x50W/40 with a small heat-sink attached to its top side PowerPad. All three devices share the same footprint enabling a single PCB to be used across different power levels. The TPA31xxD2 advanced oscillator/PLL circuit employs a multiple switching frequency option to avoid AM interferences; this is achieved together with an option of Master/Slave option, making it possible to synchronize multiple devices. The TPA31xxD2 devices are fully protected against faults with short-circuit protection and thermal protection as well as over-voltage, under-voltage and DC protection. Faults are reported back to the processor to prevent devices from being damaged during overload conditions. TDA7498E 160-watt + 160-watt dual BTL class-D audio amplifier Feature 160-W 160-W output power at THD 10% with R₁ = 4 £2 and Vcc = 36 V 1 x 220 W output power mono parallel BTL at THD 10% with R = 312 and Vcc = 36 V Wide-range single-supply operation (14-36 V) High efficiency (n=85%) Parallel BTL function using the MODE pin Four selectable, fixed gain settings of nominally 23.8 dB, 29.8 dB, 33.3 dB and 35.8 dB Differential inputs minimize common-mode noise Standby and mute features Smart protection Thermal overload protection Small offset less than 20 mV Description The TDA7498E is a dual BTL class-D audio. amplifier with a single power supply designed for home systems and active speaker applications. It comes in a 36-pin PowerSSO package with exposed pad up (EPU) to facilitate mounting a separ
