ELECTRICAL CHARACTERISTICS
Over recommended operating free-air temperature range at TA = –40°C to +125°C, AVDD = 5V, BVDD = 3V, VREF = internal +2.5V, fCLK = 10MHz, and fSAMPLE = 500kSPS,
unless otherwise noted.
NOTES: (1) All values are at TA = +25°C.
(2) Ideal input span; does not include gain or offset error.
(3) LSB means Least Significant Bit, with VREF equal to +2.5V; 1LSB = 76μV.
(4) Specified for 14-bit no missing code.
(5) Specified for 15-bit no missing code.
(6) Measured relative to an ideal, full-scale input (+IN – (–IN)) of 4.9999V. Thus, gain error does not include the error of the internal voltage reference.
