Temperature ranges are as follows: J, K versions; 0 C to +70 C
1 LSB = 4.88 mV for 0 V to +1.25 V range, 9.76 mV for 0 V to +2.5 V and 1.25 V ranges and 19.5 mV for +2.5 V range.
See Terminology.
Includes internal voltage reference error and is calculated after offset error has been adjusted out. Ideal unipolar last code transition occurs at (FS – 3/2 LSB). Ideal bipolar last code transition occurs at
Exact frequencies are 101 kHz and 384 kHz to avoid harmonics coinciding with sampling frequency.
Rising edge of BUSY to falling edge of ST. The time given refers to the acquisition time, which gives a 3 dB degradation in SNR from the tested figure.
Sample tested at +25 C to ensure compliance.
Except where noted, specifications apply for all ranges including bipolar ranges with dual supply operation.
