Part Number: TAS5720M
Other Parts Discussed in Thread: PCM1754,

Hello

We are using DA (sigma delta) convertor PCM1754 and D amplifier TPA2005D from ti.com

Please can you help us find components that mix this two components together?

Audio input interface: I2S or SPI

Volume control interface: I2C or SPI or analog

Digital input logic: 3.3V

Sampling rate min: 19 531 sample per second

Sampling resolution: 16bit

Volume control: in dB resolution +-1dB

Vbat voltage min: 5.6V -40°C

Vbat voltage max: 16V 85°C better 18V 35°C

Output power 1W nom 1,5W max at 8 Ohm

Alternative output power 0.5W nom 1,5W max at 50 Ohm

THD for 1W 400Hz - 5kHz max 1%

    Hi there,

    TAS5720M seems to be a good match for your requirement but there are a few things that I'd like to confirm with you:

    1. Do you have the sampling rate at 19.531 kHz? That does not seem to be a common number and the minimum supported is 44.1 kHz for TAS5720M.

    2. The volume control resolution of TAS5720M is 0.5 dB/ step, which is of higher resolution than your requirement.

    Thank you!

    Best regards,
