TPA2013D1: Vn Output integrated noise floor

Gene Qiu

Part Number: TPA2013D1

Hi Team,

On datasheet, I can see Vn Output integrated noise floor @Av = 6 dB (2V/V), what about Vn Output integrated noise floor @Gain at 6V/V, 10V/V? gene-qiu@ti.com

Hi, Gene,

The integrated noise floor levels at 6V/V and 10V/V are (typically) 36uVrms and and 40uVrms respectively.

Hi Luis,

Thank you for your answer.

Could you explain more about what could influence output integrated noise levels? Since for TPA3130 the Vn is 65uV, while in TPA3131 it is 70uV at Gain=20dB, compared with TPA2013D1.

Best Regards

Hi, Gene.

This is usually associated to the internal activity in the device. Since the TPA3130 and the TPA3131 are stereo devices, they have more internal modulation blocks and activity inside the IC. The TPA2013D1 is a mono device, so it has less modulation blocks.
