ELECTRICAL CHARACTERISTICS—MAX1109 (continued)
(VDD = +4.5V to +5.5V; unipolar input mode; COM = GND, fSCLK = 500kHz, external clock (50% duty cycle); 10 clocks/conversion
cycle (50ksps); 1F capacitor at REF, external +4.096V reference at REF; TA = TMIN to TMAX; unless otherwise noted. Typical values
are at TA = +25°C.)

PARAMETER
Note 1: 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 2: See Typical Operating Characteristics.
Note 3: VREF = +2.048V (MAX1108), VREF = +4.096V (MAX1109), offset nulled.
Note 4: Common-mode range (CH0, CH1, COM) GND to VDD.
Note 5: Conversion time defined as the number of clock cycles times the clock period; clock has 50% duty cycle (Figures 6 and 8).
Note 6: REF supplies typically 2.5mA under normal operating conditions.
Note 7: External load should not change during the conversion for specified accuracy.
Note 8: Power consumption with CMOS levels.
Note 9: Power-down test performed using the following sequence 1) SHDN 5bit = 0 in the configuration register; 2) Wait for 10
SCLK cycles to complete current conversion; 3) Measure shutdown current with CS, SCLK, DIN = VDD or GND.
Note 10: Measured as
VFS(2.7V) - VFS(3.6V) for MAX1108, and measured as VFS(4.5V) - VFS(5.5V) for MAX1109.
Note 11: 1F at REF, internal reference settling to 0.5LSB.
Typical Operating Characteristics
(VDD = +3.0V (MAX1108), VDD = +5.0V (MAX1109); external conversion mode; fSCLK = 500kHz; 50ksps; external reference; 1F at
REF; TA = +25°C; unless otherwise noted.)
