Load-Driving Capability
The MAX4240–MAX4244 are fully guaranteed over tem-
perature and supply voltage to drive a maximum resis-
tive load of 10k
to V
CC
/ 2, although heavier loads can
be driven in many applications. The rail-to-rail output
stage of the amplifier can be modeled as a current
source when driving the load toward V
CC
, and as a cur-
rent sink when driving the load toward V
EE
. The magni-
tude of this current source/sink varies with supply
voltage, ambient temperature, and lot-to-lot variations
of the units.
Figures 7a and 7b show the typical current source and
sink capability of the MAX4240–MAX4244 family as a
function of supply voltage and ambient temperature.
The contours on the graph depict the output current
