A 1.25 V reference is provided to bias the amplifier output to the mid-span of the ADC conversion range, which is set with a 2.5 V external voltage reference. Hardware shutdown of the PGA and voltage reference supply to the accelerometer and filter sections conserves limited ... and remotely programmable digital filter is implemented using the hardware multiplier within the MSP430 microcontroller.
