ADC3910D025: Reset register reads 0x20 after reset

Mohammad Abu Khater

Part Number: ADC3910D025

Hello,

According to the datasheet (P. 54) the reset register value after resetting the IC should be 0x00. When we read the register, however, it is always 0x20. This occurs after soft reset (SPI) or hard reset pin. The reset is performed successfully. We verified that by checking other registers, they go back to their original value after changing them. We did wait much longer than the recommended 2000 clocks between resetting the register and reading it back.

Could you please check if the reset register always reads 0x20?

Thanks!

Thank you for letting us know.
No other details are relevant here. Just the ADC's SPI write and read.

Hi Mohammad,

Sorry for the delay. This is a mistake on the datasheet that will get corrected. The 0x20 value at reset is correct.

Best,
