Note 1: Tested at V
Note 2: Relative accuracy is the analog value’s deviation (at any code) from its theoretical value after the full-scale range is
Note 3: Internal reference, offset nulled.
Note 4: On-channel grounded; sine-wave applied to all off-channels.
Note 5: Conversion time is defined as the number of clock cycles multiplied by the clock period; clock has 50% duty cycle.
Note 6: Guaranteed by design. Not subject to production testing.
Note 7: Common-mode range for analog inputs is from V
Note 8: External load should not change during the conversion for specified accuracy.
Note 9: Shutdown supply current is measured with VL at 3.3V, and with all digital inputs tied to either VL or GND (Figure 12c);
Note 10: Logic supply current is measured with the digital outputs (DOUT and SSTRB) disabled (CS high). When the outputs are
Note 11: Measured at V
Note 12: Measured at VL = 2.7V and VL = 3.6V.
