These specifications need to be added based on performance of final silicon.
NOTES: (1) All specifications in dB are referred to a full-scale input range. (2) Over this range, total error will typically not exceed
±
1LSB. (3) In this mode, the ADS7832
acquires the input signal for five clock cycles after a start command, before the input is held and conversion begins. (4) LSB means Least Significant Bit. For a 0V to
5V input range, one LSB is 1.22mV. For a 0V to 2.5V input range, one LSB is 610
