Shutdown Mode
The MAX4041 (single) and MAX4043 (dual) feature a
low-power shutdown mode. When the shutdown pin
(SHDN) is pulled low, the supply current drops to 1A
per amplifier, the amplifier is disabled, and the outputs
enter a high-impedance state. Pulling SHDN high or
leaving it floating enables the amplifier. Take care to
ensure that parasitic leakage current at the SHDN pin
does not inadvertently place the part into shutdown
mode when SHDN is left floating. Figure 4 shows the
output voltage response to a shutdown pulse. The logic
threshold for SHDN is always referred to VCC / 2 (not to
GND). When using dual supplies, pull SHDN to VEE to
enter shutdown mode.
Load-Driving Capability
The MAX4040–MAX4044 are fully guaranteed over tem-
perature and supply voltage to drive a maximum resis-
tive load of 25k
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-
tude of this current source/sink varies with supply
voltage, ambient temperature, and lot-to-lot variations
of the units.
Figures 5a and 5b show the typical current source and
sink capability of the MAX4040–MAX4044 family as a
function of supply voltage and ambient temperature.
The contours on the graph depict the output current
value, based on driving the output voltage to within
50mV, 100mV, and 200mV of either power-supply rail.
