ADS131A04: M0, M1, M2 Config Pins

Aaron Lancour

Part Number: ADS131A04

Is it necessary to use 1k ohm resistors for the M[0..2] pins as stated in section 9.5.2 SPI Interface, second paragraph of the data sheet? Is it ok to use 4.7k, 10k instead?

Thank you,

Aaron

Hi Aaron,

1k or less is recommended in order to prevent the M[2:0] pins from latching in the wrong state during power-up. You can also tie the pins directly to the supply if you prefer.
