Other Parts Discussed in Thread: LM49450 Looking at the LM49450 specification for Vih on the digital inputs, I read a minimum of +2.8V is required.
However the datasheet also says that IOVDD can be as low as +1.8V: “ IOVDD powers the I2S and I2C,…
Other Parts Discussed in Thread: LM49450 Dear Team:
Our customer used LM49450 in smart monitor, butgot ESD test failed, when ESD test +/-15kV, the audio speaker out got audio noise continuous. We have checked the ESD energy coupling to I2S bus as attachedfile…
Other Parts Discussed in Thread: LM49450 , TAS5717 Dear Team:
Our customer used LM49450 in monitor audio solution, but headhone got pop noise.
When we disable I2S input pinto ground, we stil got pop noise at power Off/ ON.
We tried to turn on Mute off/…
Other Parts Discussed in Thread: LM49450 For Nvidia:
We have a question regarding the DAC Amp LM49450. Is there a way to tune the charge pump (either through registers or capacitor value) such that the speaker volume can be louder? We have already maximized…
Other Parts Discussed in Thread: LM49450 Hi Team,
LM49450 has the short circuit protection and the thermal overload protection. But there is no detail description for them in the datasheet.
How can we do to be recovered from the shutdown state, when the…
Other Parts Discussed in Thread: LM49450 We are using the LM49450 Audio DAC in a new product that we are having problems with.
We are using the device in I2S Slave mode and playing a 44.1 KHz 16-bit stereo track with an approximate 12 MHz MCLK. We are not…
Other Parts Discussed in Thread: LM49450 Hi There,
Presently am using LM49450 DAC, we are getting some noise in the speaker. Moreover, when we measured the clock in speaker, it is more than 250 Mhz
We have the MCLK as 12.3 Mhz. Could you please provide…
Part Number: TLV320DAC3100 Other Parts Discussed in Thread: LM49450 Hi I was searching for the Code example or driver for TLV320DAC3100 that i can use with arm cortex M controllers. So far i was able to get linux drivers only. that is complex to understand…
Other Parts Discussed in Thread: LM49450 The LM49450 datasheet states that this part implements Short Circuit and therrnal protection. I had a board where the speaker outputs were shorted. The Codec was damaged and required repalcement. Is there limitations…
