Specifications same as ADS7852Y.
NOTES: (1) LSB means Least Significant Bit, with V
equal to +2.5V, one LSB is 1.22mV. (2) Measured relative to an ideal, full-scale input of 4.999V. Thus,
gain error includes the error of the internal voltage reference. (3) Calculated on the first nine harmonics of the input frequency. (4) If the internal reference is required
to source current to an external load, the reference voltage will change due to the internal 10k
resistor. (5) Can vary
±
30%. (6) See Timing Diagrams for further
detail.
