Note 1:
Accuracy specifications tested at VDD = 5.0V. Performance at power-supply tolerance limits guaranteed by Power-Supply
Rejection test. Tested for the ±10V (MAX196) and ±4.096V (MAX198) input ranges.
Note 2:
External reference: VREF = 4.096V, offset error nulled, ideal last code transition = FS - 3/2LSB.
Note 3:
Ground “on” channel; sine wave applied to all “off” channels.
Note 4:
Maximum full-power input frequency for 1LSB error with 10ns jitter = 3kHz.
Note 5:
Guaranteed by design. Not tested.
Note 6:
Use static loads only.
Note 7:
Tested using internal reference.
Note 8:
PSRR measured at full-scale.
Note 9:
External acquisition timing: starts at data valid at ACQMOD = low control byte; ends at rising edge of WR with ACQMOD
= high control byte.
Note 10: Not subject to production testing. Provided for design guidance only.
Note 11: All input control signals specified with tR = tF = 5ns from a voltage level of 0.8V to 2.4V.
Note 12: tDO is measured with the load circuits of Figure 2 and defined as the time required for an output to cross 0.8V or 2.4V.
Note 13: tTR is defined as the time required for the data lines to change by 0.5V.
TIMING CHARACTERISTICS
(VDD = 5V ±5%; unipolar/bipolar range; external reference mode, VREF = 4.096V; 4.7F at REF pin; external clock, fCLK = 2.0MHz
with 50% duty cycle; TA = TMIN to TMAX; unless otherwise noted.)
ELECTRICAL CHARACTERISTICS (continued)
(VDD = 5V ±5%; unipolar/bipolar range; external reference mode, VREF = 4.096V; 4.7F at REF pin; external clock, fCLK = 2.0MHz
with 50% duty cycle; TA = TMIN to TMAX; unless otherwise noted. Typical values are at TA = +25°C.)
