Other Parts Discussed in Thread: TLV320DAC3120, TLV320DAC3101, TAS2505

Dear TI Team,

Can an one of you suggest an Audio Amplifier which can drive both Speaker and Head Phone, which has programmable gain (through I2C)?

Thanks and regards,

Hi Paul,

I assume you're looking for digital input devices, correct?
You may be interested in devices like TLV320DAC3101 for stereo outputs or TLV320DAC3120 for mono.

Please let us know more details about your application like input signal, load impedance, how much power is required.

Best regards,

Hi Ivan,

Actually I was looking for analog input devices - Sorry for the confusion since I did not mention it explicitly.

Hi Paul,

Thanks for the feedback.

The TLV320DAC devices I mentioned are still options for this, these have analog inputs in parallel to the DAC, and both connected to Speaker and Headphone output.
Similar option would be TAS2505.

Some other options, although not as supported in terms of EVM, documentation, etc are:
