One case may cause beat noise: The input signal pick up switching signal of different frequency and amplified by following amplifier. 1) the input amplify stage is non-linear at high frequency, beat frequency is generated. 2) the modulation stage is non…
Thanks Nate for your answer
I take a 20w stereo class d as TPA3100D2 . In the data sheet it can output 15W/ch 4 ohms. If i do the BTL link, do i can have 30W in a single chanel of 2 ohms.
Is there a limite to put 2 x TPA3100D2 in BTL to have 60W in…
Hi, Bill,
2-ohms is not a typical speaker impedance our customers use, and is a much more challenging load to drive.
You could use something like TPA3100D2 set up in parallel-BTL operation as shown in figure 4 of http://focus.ti.com/lit/an/sloa121a/sloa121a…
Other Parts Discussed in Thread: TPA3110D2 , TPA3100D2 All,
I am looking for R2A15122(Renesas) replacement, any class D audio amp from TI to replace?
Thanks,

Other Parts Discussed in Thread: TPA3100D2 , TPA3110D2 Audio power amplifiers (APA's) share a number of PCB layout requirements. Class-D APA's offer far better efficiency than class-AB, and they achieve this with switching outputs. As a result they have…
Other Parts Discussed in Thread: TPA3106D1 , TPA3100D2 Hi All,
we are designing an ultrasonic generator with TPA3106D1.
This works fine. We already have experience with TI amplifiers and the previous generation was made from a TPA3100D2.
At this moment…
Hey, Ken,
But, can you visualize whirled peas?
Seriously, page 17 of the TPA3100D2 data sheet, continuing on to page 18 has a decent description of BD-mode class-D amplification. The main benefit it brings is a vast reduction in ripple current in the…
Hi, Jon,
I am not super familiar with the TAS5518 (it's from another group inside TI), but I am 99.3% sure that it uses standard run of the mill PWM. What makes you think it's PDM?
The one thing that may be confusing is the fact that we have…
Other Parts Discussed in Thread: TPA3100D2 , TLV320AIC34 Hi,
Im building an audio application in which I use the TLV320AIC34 codec as an input switch, microphone amplifier and tone control. the output i connected to a TPA3100D2 power amplifier.
Out off…
Other Parts Discussed in Thread: TLV320AIC34 , TPA3100D2 Hi,
I'm building a amplifier based on the TLV320AIC34 codec. The problem is that there are a lot of crosstalk - even if the codec has been resat, and all of the input/outputs therefore are deactivated…
