LIS3DSH - analogue to digital converter

The LIS3DSH has a three channel 10 bit A/D converter but I can't find any information on it.

What is the accuracy? (I could tie one channel to a voltage reference for calibration if necessary)

What is the input voltage range?

What is the maximum input current? (will I need to buffer the channels)

I suppose you mean LIS3DH, because LIS3DSH does not have auxiliary ADC.

Then you can check this: [DEAD LINK /public/STe2ecommunities/mems_sensors/Lists/Accelerometers/Flat.aspx?RootFolder=/public/STe2ecommunities/mems_sensors/Lists/Accelerometers/LIS3DH%20ADC%20Specifications&FolderCTID=0x01200200770978C69A1141439FE559EB459D7580004224A862E061BB4BADDEF313D70857E6&TopicsView=https://my.st.com/public/STe2ecommunities/mems_sensors/Lists/Accelerometers/AllItems.aspx&currentviews=316]https://my.st.com/public/STe2ecommunities/mems_sensors/Lists/Accelerometers/Flat.aspx?RootFolder=%2fpublic%2fSTe2ecommunities%2fmems_sensors%2fLists%2fAccelerometers%2fLIS3DH%20ADC%20Specifications&FolderCTID=0x01200200770978C69A1141439FE559EB459D7580004224A862E061BB4BADDEF313D70857E6&TopicsView=https%3A%2F%2Fmy%2Est%2Ecom%2Fpublic%2FSTe2ecommunities%2Fmems_sensors%2FLists%2FAccelerometers%2FAllItems%2Easpx&currentviews=316

Hi, Miroslav,

I have same question about the ADC's accuracy, but I couldn't open the link above.

Could you send me a updated link? or, if just let me know the ADC's accuracy. Thanks.

Thanks 1,200mV, +-400mV, 8 or 10 bit depending on mode. The input current is not mentioned though so I will assume that it does need buffering. Thanks for correcting the part number.
