Note 1: Static accuracy tested without load.
Note 2: Linearity is tested within 20mV of GND and AVDD
,
allowing for gain and offset error.
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 < V
DVDD
- 0.6V
or VI > 0.5V. At VI = 2.2V with V
DVDD
= 5.25V, this current can be as high as 2mA. The SPI inputs are CMOS-input level com-
patible. The 30MHz clock frequency cannot be guaranteed for a minimum signal swing.
Note 7: Excess current from AVDD is 10mA when powered without DVDD. Excess current from DVDD is 1mA when powered without
AVDD.
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.
