The 4W that TPA3131D2RHBR has AM interference to control a function, 25W does not have filter D kind stereo amplifier

The 4W that TPA3131D2RHBR has AM interference to control a function, 25W does not have filter D kind stereo amplifier

Product model: TPA3131D2RHBR

Product brand: Apparatus of TI/ heart state

The product encloses: VQFN32

Product function: Stereo amplifier

TPA3131D2RHBR character

● supports a variety of output configuration

Bridge of 7.4V voltage, 8 Ω receives load (the power below BTL) laden condition is 4W (TPA3130D2 of 2 × )

The power below laden condition of BTL of 19V voltage, 8 Ω is 25W (TPA3132D2 of 2 × )

Limits of ● wide voltage: 4.5V comes 26V

● car casts load compatible

● efficient D kind move

Hold concurrently > the power efficiency of 90% and character of loss of low altitude idle, need not radiator can be stabilized move

Advanced modulation system is configured

● much reopen closes frequency

AM is restrained

Mode of principal and subordinate is synchronous

Be as high as the switch frequency of 1.2MHz

● uses the framework of feedback power level that has tall PSRR, reduced PSU demand

● but limitation of process designing power

● differs cent and Chan Duan to input

● stereo mode and odd track mode (use odd filter odd track to configure)

● moves by power supply of only power source, reduced component amount

● is compositive provide those who have erroneous report function to protect circuit oneself, had included to press among them, owe pressure, overheat, dc detects and the protection such as short circuit

● comes loose heat increases model enclose

32 cite a base ultrathin model all directions is compressed without down-lead (VQFN) is enclosed (below solder Pan Chao)

● – 40 ° C comes limits of temperature of environment of 85 ° C

TPA3131D2RHBR explains

TPA3131D2RHBR is the level of power of amplifier of efficient stereo number that is used at drive loudhailer, power of peak value drive is as high as 2x42W/4 Ω . The printed circuit of TPA3131/32D2 board (does PCB) pass bottom PowerPAD? Undertake coming loose heating up, need not use radiator, can offer Ω of 4W/8 of 2 × continuously at the same time (TPA3131D2) comes Ω of 25W/8 of 2 × (the output power inside TPA3132D2) limits.

TPA3131D2RHBR advanced oscillator / PLL circuit uses option of much switch frequency to restrain AM interference; When option of synchronism of mode of tie-in use principal and subordinate, still can make many parts of an apparatus realize synchronism.

TPA3131D2RHBR is aimed at short circuit, overheat, press too, owe press and the breakdown such as dc provided overall protection. Below overload circumstance, parts of an apparatus can give processor breakdown case report, avoid oneself to suffer damage thereby.

Characteristic and compatible parts of an apparatus includes: 50W TPA3116D2 of 2 × (on PowerPAD face) , 15W TPA3130D2 of 2 × (PowerPAD is gadarene) with 30W TPA3118D2 of 2 × (PowerPAD is gadarene)
