Hi there,
I was looking through the LME49724 datasheet, and figure 53 gives a nice example of pairing the LME49724 for an ADC input, however, I'm after some assistance to design this product into my circuit so it can act as a balanced cable driver at the output of my differential DACs.
My DACs are for a balanced audio application. They have 24-bit resolution, a full-scale output voltage of 1.76 Vrms (4.96 V p-p), and a common-mode reference output of 1.5 V.
Can you please help me with a product recommendation and design recommendation to achieve my requirements?
Many thanks!
Mark
Hi Mark,
I'm checking along with other teams for further recommendations, will get back to you with some options by tomorrow.

That's great! Thanks, Ivan. I look forward to hearing back from you and your team!
Hi Mark,
Sorry for late response, I'm still looking into this.
This and other tasks taking longer than planned, will try to send some further comments as soon as possible.

Hi Mark,
You may look into OPA1637, most of line drivers at Audio portfolio are single-ended, so it would be a better idea to look into op amps rather than line-drivers.

Thanks, Ivan. I'll look at the spec's for the device now. I'm assuming it would be recommended also based on my description in my initial post?
Kind regards,
Mark
Hi Ivan, it appears that device accepts lower voltage inputs (~0.5V). Is there a similar device that can accept higher audio input voltages?
Thanks,
Mark
Hi Mark,
Your input voltage range is based on your supply voltage.
There must be a typo in Abs Max Ratings table, it should be based on Vs, not +/-0.5V by itself.

No problem, let us know if there are further questions.
