LM4911Q-Q1: new device recommendation

Hi Sherry,

There is no other Q1 headphone amplifier at this moment, let me check if we'll have something new.
In addition, can customer use digital input instead of analog inputs? If they can use digital input perhaps TLV320AIC3254-Q1 can be an option as this device has headphone output.

Another option would be to use op amps, some options are below:

• OPA1641-Q1
• OPA1612-Q1
• OPA1662-Q1
• OPA1642-Q1

These op amps have rail-to-rail outputs, and they have different input architectures (Bipolar or JFET) and supply voltage ranges.

Hi Ivan,

The customer needs High Fidelity Stereo Headphone Amplifier, and they are not cost sensitive. Please check whether we have new devices. I will recommend the devices that you suggest to the customer. And I will also confirm with the customer if they can use catalog rating.

Thanks & Best Regards,

Sherry

Sherry,

Unfortunately there are no new automotive graded headphone amplifiers coming out.

Please let us know if customer finds the op amps suitable and/or confirm if they can use catalog devices so we can suggest some of them.
