ELECTRICAL CHARACTERISTICS (continued)
(VDD = +2.7V to +5.25V, VREF = 2.5V, 0.1F capacitor at REF, fSCLK = 2.17MHz, 16 clocks/conversion cycle (108ksps),
CH- = GND for MAX159, TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C.)
TIMING CHARACTERISTICS (Figure 7)
(VDD = +2.7V to +5.25V, VREF = 2.5V, 0.1F capacitor at REF, fSCLK = 2.17MHz, 16 clocks/conversion cycle (108ksps),
CH- = GND for MAX159, TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C.)
Note 1: Tested at VDD = +2.7V.
Note 2: Relative accuracy is the deviation of the analog value at any code from its theoretical value after full-scale range has been
calibrated.
Note 3: Offset nulled.
Note 4: The on channel is grounded; the sine wave is applied to off channel (MAX157 only).
Note 5: Conversion time is defined as the number of clock cycles times the clock period; clock has 50% duty cycle.
Note 6: The common-mode range for the analog inputs is from GND to VDD (MAX159 only).
Note 7: ADC performance is limited by the converter’s noise floor, typically 300Vp-p.
Note 8: Guaranteed by design. Not subject to production testing.
Note 9: Measured as VFS(2.7V) - VFS(5.25V).
