DESCRIPTION
To minimize total power consumption, the ADC08831/ADC08832 automatically go into low power mode whenever they are not performing conversions. A track/hold function allows the analog voltage at the positive input to vary during the actual A/D conversion. The analog inputs can be configured to operate in various combinations of single-ended, differential, or pseudo-differential modes. The voltage reference input can be adjusted to allow encoding of small analog voltage spans to the full 8-bits of resolution.
