Hi Jose,
Could you help clarify if LM4670 is with output short protection? I did an experiment to short VO1 and VO2 when playing sound, the same failure symptom (VO2 short to GND) can be reproduced and the chip is damaged.
I checked the LM4670 datasheet…
Part Number: LM4670 Are there any reports on the reliability LM4670? I am need to create a MTBF / FIT calculation for a circuit with this chip and cannot find any helpful information.

Hi,
I found TI LM4670 SPK AMP is with output noise after SHUTDOWN=H without any input signals.
Is this a known issue? Is there any workaround to fix this? Or any Pin to pin alternative…
Hello,
How much current and short pulse duration of the short circuit limitation that without chip broken. Could we provide the spec. and more detail about short circuit working behavior. There is no more description about that in datasheet or block…
Other Parts Discussed in Thread: LM4670 , TPA2013D1 Hello,
LM4670 and TPA2013D1 all don't have short circuit protection, right?
What is better long term supply to customer between tow device? Thank you.

Other Parts Discussed in Thread: LM4670 , TPA2034D1 Hi !
I'm working with the LM4670. The output stops oscillating frequently , sometimes Vo2,Vo1 or both. So the speaker get just pure dcv.
It happens with the input tied to gnd also with audio signal. …

What are your thoughts???
I know LM4675 is more expensive and has only 2.7W.
The LM4670 is cheaper and has 3W.
The toy is played with outdoors, so I would like it to be loud…
Other Parts Discussed in Thread: LM4670 , LM4675 Can somebody help me add a volume adjustment potentiometer to the LM4670 amplifier?
The input is single ended. I will be following Figure 29 or Figure 30 on page 13, 14 of the datasheet.
What do you recommend…
Hello SHH,
We have LM4670-Q1 which is designed for active bridge rectification for AC input upto 42V maximum.
This is a zero Iq device and does not drain battery in power critical applications.
4x MOSFET + 4x LM74670-Q1 can be use to achieve full bridge…
