Re: Looking for a Compact Accelerometer
Hi Jhin, It seems like you are looking for a system solution but not a single chip. ADXL362 is a 3mm x 3.25mm x 1.06mm 3 axis digital output accelerometer. It consumes around 1.8uA current @ 2V supply,...

View ArticleRe: AD7195: ratiometric reference usage
My Sensor supply voltage is 8V and not 5V.As I can not give 8V directlly to the AD7195 I shall reduce it to 3.75V (and not 5V because of the PGA that need supply).I will look for other solutions.
