NOTES
1
Except where noted, specifications apply for all ranges including bipolar ranges with dual supply operation.
2Temperature ranges are as follows: J, K versions; 0
°C to +70°C
A, B versions; –40
°C to +85°C
S, T versions; –55
°C to +125°C
31 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.
4See Terminology.
5Includes 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
(FS/2 – 3/2 LSB).
6Exact frequencies are 101 kHz and 384 kHz to avoid harmonics coinciding with sampling frequency.
7Rising 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.
8Sample tested at +25
°C to ensure compliance.
Specifications subject to change without notice.
(VDD = +5 V
5%; VSS
1 = RANGE = AGND
DAC = AGNDDAC = DGND = 0 V; fCLK = 5 MHz external unless other-
wise noted. All specifications TMIN to TMAX unless otherwise noted.) Specifications apply to Mode 1 interface.
