Part Number: LM48580 Hello, we are working on integrating a MEMS speaker into a product. The LM48580 amplifier is used in this application to drive a MEMS speaker. The MEMS speaker requires a DC offset on the driving signal. For this purpose we use the…
Part Number: LM48560 Other Parts Discussed in Thread: LM48580 Hi exerts,
I think LM48560/ LM48580 do not have mute function or popless mute.
Is my understanding correct?

Part Number: LM48580 Hi
We are using LM48580 and need to measure the quiescent power supply, but it is higher than expected, in LM48580 datasheet, the typical quiescent power consumption at 3.6V should be 2.7mA and maximum is 4mA. But we measured at…
Part Number: LM48580 Other Parts Discussed in Thread: TPS62133 , Did this issue get resolved? I have very similar behavior but there was no update after the conversation when private.

Hi Dierk,
LM48580 has an EVM available, perhaps it would be good idea to use one to test it with the proposed inductors.
The main constraint is that rated current seems to be a bit too low for those inductors, you can compare them to the ones suggested…
Part Number: LM48580 Hi All,
My customer intend to use the LM48580 and have below questions:
1. Is VOUT+/-(VBST) voltage adjustable?
2. Based on the spec, may i confirm that the Vp-p are +15V and -15V?
Thank you for your help.
Best Regard…
Part Number: LM48580 Hello,
I've an application who we need to drive an ultrasonic transducteur (ex prowave ep18) with a frequency modulated signal.
Then I want to know if the LM48580 could be used for driving EP18 transducer, the frequency will vary…
Hi BR Holger,
Pspice model also has 10 pins only.
When we do our modeling, we don't model every single thing within the part. For this part, we focus on the functionality of the signal path of the part. As such we only model the Boost Converter…
Part Number: LM48580 Other Parts Discussed in Thread: LM48560 , DRV2700 , TIDA-00376 Hello guys,
One of my customers is evaluation LM48580 usint the device EVM for their next products. And they are going to drive using a piezo speaker which has the…
Part Number: LM48580 For the Gain Input Resistance parameter in the datasheet, I'm assuming this is referring to a maximum external pullup or pulldown resistor value, as opposed to an internal resistance. Please confirm. Is there any reason not to hard…
