ADM2587E interface

rajkumar on Oct 7, 2020

Hi Iam using ADM2587E for UART to RS485 conversion. but at temperature greater than 40 degree celcius iam seing a noise and data corruption at the output of ADM2587E.

Can anyone please help me out to resolve the issue.

Hi Rajkumar,

The leading cause of noise issues would be inadequate power supply decoupling. These decoupling capacitors must be placed as close to the DUT as possible.

Can you confirm your design has the recommended decoupling as shown in Figure 35 of the ADM2582E/ADM2587E datasheet? These capacitors should be low ESR MLCC capacitors, polarized tantalum capacitors are not suitable.
