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: LM48560 Hi
The current Buzzer frequency is 1K to test the Buzzer sound is no problem But the customer also has a 2.9K 92dB Buzzer, we turned the Gain to the maximum and the sound is still very low In addition to changing the hardware and…
Part Number: LM48560 I have a setup with LM48560TLEVAL powered with 3.3V, connected to piezoelectric speaker (UT-P2018) and driven with a MCU 3.3V PWM signal but reduced to 0.9V through voltage divider.
I apply 4 different flavors of PWM signals: pure…
Part Number: LM48560 Hi there,
The minimum operating voltage is 2.7V.
Whilst I appreciate that the device behaviour is not specified outside the operating voltage range,
is it likely that holding the nSHDN pin at 0V will keep the device in a low current…
thank you, I am aware of this.
However, ultrasonic speakers are piezo speakers and require a driver han can handle capaciive loads, The LM48560 can handle the bandwidth but indeed at ultrasonic frequencies the impedance of such speakers drops. I have…
Part Number: LM48560 Hi there,
Two LM48560 questions please:
I am only using IN1 - what should I do with IN2+ and IN2-:
* tie them to 0V,
* leave them floating, or
* Something else?
Does H/W Shutdown still work in S/W Mode, giving 0.1uA typ (2uA max)…
Hi, Yaita-san,
I apologize for the confusion, I made a confusion with the LM48560 capacitance value, which cannot handle high capacitance level. The LM48580 will be a good option to handle this capacitance level.
Please let me know if you have additional…
Part Number: LM48560 Hi Team,
My customer is asking what will happen if SHDN pin (B2) is shorted to Out- pin (B1)? Due to soldering challenge for BGA package, B1 pin and B2 pin might sometime shorted together. Engineering side would like to know what…
Part Number: LM48560 Hi Sirs, Would you pls advise the load capacitance range of the LM48560 ceramic speaker driver? There are 1.5uF, 1uF, 0.6uF test curves on the datasheet, while the datasheet does not specify capacitance range. My customer got attenu…
