Load-Driving Capability
The MAX4240–MAX4244 are fully guaranteed over tem-
perature and supply voltage to drive a maximum resis-
tive load of 10k
Ω to VCC / 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 VCC, and as a cur-
rent sink when driving the load toward VEE. The magni-
