The document explains a biasing scheme for the AD7575 Analog-to-Digital Converter (ADC) to accommodate input signals referenced to a pseudo-ground. This setup ensures linear operation of the signal conditioning circuitry over the complete input signal range by biasing the ADC's analog ground (AGND) pin above system ground.
The device achieves a fast conversion time of 5 us.
The recommended reference voltage is +1.23V.
The input range is from 0 V to +2.46 V.
