I am designing an IMU Board using LY530ALH and LPR530AL as gyros. I want this board to connect as a doughterboard via I2C and SPI to a uC board that i already have.
In order to do that i have to put an ADC in this board and do SPI. I am considering to use two AD7924 ADCs (X, 4X, Y, 4Y) (Z, 4Z, TEMP, ).
The questions are
1) do you consider that a good solution? or should i use a diferent ADC.
2) I am thinking to drive ADCs VREF with an AD780 that provides a 2.5V reference and temperature measurement. Is this desirable or Should i put and OPAmp and double 1.23V gyro out Vref from the and usa that as ADC RefIn.
