TIMING CHARACTERISTICS
(VDD = +5V ±5%, VL = 2.7V to 3.6V, VSS = 0V or -5V ±5%, TA = TMIN to TMAX, unless otherwise noted.)
Note 1:
Tested at VDD = 5.0V; VSS = 0V; unipolar-input mode.
Note 2:
Relative accuracy is the analog value’s deviation (at any code) from its theoretical value after the full-scale range is calibrated.
Note 3:
MAX1202—internal reference, offset nulled; MAX1203—external reference (VREF = 4.096V), offset nulled.
Note 4:
On-channel grounded; sine wave applied to all off-channels.
Note 5:
Conversion time is defined as the number of clock cycles multiplied by the clock period; clock has 50% duty cycle.
Note 6:
Guaranteed by design. Not subject to production testing.
Note 7:
Common-mode range for analog inputs is from VSS to VDD.
Note 8:
External load should not change during the conversion for specified accuracy.
Note 9:
Shutdown supply current is measured with VL at 3.3V, and with all digital inputs tied to either VL or GND;
REFADJ = GND. Shutdown supply current is also dependent on VIH (Figure 12c).
Note 10: Logic supply current is measured with the digital outputs (DOUT and SSTRB) disabled (CS high). When the outputs are
active (CS low), the logic supply current depends on fSCLK, and on the static and capacitive load at DOUT and SSTRB.
Note 11: Measured at VSUPPLY + 5% and VSUPPLY - 5% only.
Note 12: Measured at VL = 2.7V and VL = 3.6V.
