_______________________________________________________________________________________
Note 1: Accuracy specifications tested at VDD = +5.0V. Performance at power-supply tolerance limit is guaranteed by power-supply
rejection test.
Note 2: External reference: VREF = 4.096V, offset error nulled. Ideal last-code transition = FS - 3/2 LSB.
Note 3: Ground “on” channel; sine wave applied to all “off” channels. VIN = ±5V (MAX1270), VIN = ±4V (MAX1271).
Note 4: Guaranteed by design, not production tested.
Note 5: Use static external loads during conversion for specified accuracy.
Note 6: Tested using internal reference.
Note 7: PSRR measured at full scale. Tested for the ±10V (MAX1270) and ±4.096V (MAX1271) input ranges.
Note 8: Acquisition phase and conversion time are dependent on the clock period; clock has 50% duty cycle (Figure 6).
Note 9: Not production tested. Provided for design guidance only.
TIMING CHARACTERISTICS
(VDD = +4.75V to +5.25V; unipolar/bipolar range; external reference mode, VREF = +4.096V; 4.7F at REF; external clock; fCLK =
2.0MHz (MAX127_B); fCLK = 1.8MHz (MAX127_A); TA = TMIN to TMAX, unless otherwise noted. Typical values are TA = +25°C.)
