Specifications subject to change without notice.
LSB means Least Significant Bit. With the 0 V to 2.5 V input range, one LSB is 38.15 µV.
Typical rms noise at worst-case transitions and temperatures.
See Definition of Specifications section. These specifications do not include the error contribution from the external reference.
All specifications in dB are referred to a full-scale input F
Tested in parallel reading mode.
With all digital inputs forced to DVDD or DGND respectively.
In serial interface modes, the SYNC, SCLK, and SDOUT timings are defined with a maximum load C
If the polarity of SCLK is inverted, the timing references of SCLK are also inverted.
