ADS7253: SPI baudrate

Joyce Gao

Part Number: ADS7253

Hi expert,

Do we have higher speed SPI communication ADCs? Customer wants the ADC to communicate faster, such as 5Mbps,10Mbps level. Where could I find in datasheet how fast could the ADC communication interface be? Found the timing specs as below, what baudrate for below specs of ADS7253 is? Is it 1Mbps?

Thanks

Hi PL,

Why there's no reply?

Hi Joyce,

BAUD rate is not commonly used in SPI discussions, what speed, resolution and channel count are you looking for in the end?

Hi Tom,

Customer asks what frequency ADS7253's SPI is, could you help clarify? Didn't find clear info in the DS:

Hi Joyce,

One place to start would be at the top of the electrical characteristics page. In this case the art is running at 'full speed' which means 2MSPS. SCLK can run up to 20MHz.
