TIMING CHARACTERISTICS—MAX1285 (Figures 1, 2, 8, 9) (VDD = +2.7V to +3.6V, TA = TMIN to TMAX, unless otherwise noted.) Note 1: Tested at VDD = VDD(MIN). Note 2: Relative accuracy is the deviation of the analog value at any code from its theoretical value after the full-scale range has been calibrated. Note 3: Internal reference, offset, and reference errors nulled. Note 4: Conversion time is defined as the number of clock cycles multiplied by the clock period; clock has 50% duty cycle. Note 5: External load should not change during conversion for specified accuracy. Guaranteed specification limit of 2mV/mA due to production test limitations. Note 6: Electrical characteristics are guaranteed from VDD(MIN) to VDD(MAX). For operations beyond this range, see Typical Operating Characteristics. Note 7: MAX1284 tested with 20pF on DOUT and fSCLK = 6.4MHz, 0 to 5V. MAX1285 tested with same loads, fSCLK = 4.8MHz, 0 to 3V. DOUT = full scale.
