TAA5242: SNR, Dynamic range, input range at 1.8V AVDD

Toshiro Imi

Part Number: TAA5242

Tool/software:

Hello,

While our customer is studying TAA5242 application at AVDD=1.8V condition, he has some question about device performance at AVDD=1.8V.

- SNR at A-weighted.

- Dynamic range

- Input voltage range in differential / single ended mode.

Could you please let us know these perfromance information at 1.8V AVDD.

Best regards,

Hi Imi-san,

Actually this information is in the datasheet:

Input full-scale voltage range will be reduced to 1Vrms for differential and 0.5Vrms for single-ended.

Hi Garret-san,

Thank you very much for your help and apologize of my feedback late.

As we checked in the datasheet, we could see differential SNR and DR at 1.8V AVDD though, we could not find out Single-ended SNR, DR,

Would it be possible to check if we can help this customer to find out single ended SNR, DR in 1.8V AVDD.

Best regards,

Hi Imi-san,

For single-ended inputs in 1.8 AVDD, SNR = 104dB and DR = 105dB.

Hi Garret-san,

Thank you. I understand SNR=104 db at INx single ended 1.8V AVDD, DR=105db at single ended 1.8V AVDD.
