Figure 1. Serial-Interface Timing Diagram
Note 1: Static accuracy tested without load.
Note 2: Linearity is tested within 20mV of GND and AVDD
Note 3: Codes above 2047 are guaranteed to be within ±8 LSB
Note 4: Gain and offset tested within 100mV of GND and AVDD
Note 5: Guaranteed by design.
Note 6: Device draws current in excess of the specified supply current when a digital input is driven with a voltage of VI < DVDD - 0.6V
Note 7: Excess current from AVDD is 10mA when powered without DVDD. Excess current from DVDD is 1mA when powered without
Note 8: All timing specifications are with respect to the digital input and output thresholds.
Note 9: Maximum daisy-chain clock frequency is limited to 25MHz.
