Note 1:
Accuracy specifications tested at V
DD
= 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.
External reference: V
REF
= 4.096V, offset error nulled, ideal last code transition = FS - 3/2LSB.
Ground “on” channel; sine wave applied to all “off” channels.
Maximum full-power input frequency for 1LSB error with 10ns jitter = 3kHz.
Guaranteed by design. Not tested.
Use static loads only.
Tested using internal reference.
PSRR measured at full-scale.
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 t
R
= t
F
= 5ns from a voltage level of 0.8V to 2.4V.
Note 12:
t
DO
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:
t
TR
is defined as the time required for the data lines to change by 0.5V.
