Output Stage Circuitry
The MAX9140/MAX9141/MAX9142/MAX9144 contain a
current-driven output stage as shown in Figure 4.
During an output transition, I
SOURCE
or I
SINK
is pushed
or pulled to the output pin. The output source or sink
current is high during the transition, creating a rapid
slew rate. Once the output voltage reaches V
OH
or
V
OL
, the source or sink current decreases to a small
value, capable of maintaining the V
OH
or V
OL
static
condition. This significant decrease in current con-
serves power after an output transition has occurred.
One consequence of a current-driven output stage is a
linear dependence between the slew rate and the load
capacitance. A heavy capacitive load will slow down a
voltage output transition. This can be useful in noise-
sensitive applications where fast edges may cause
interference.
Applications Information
Circuit Layout and Bypassing
The high-gain bandwidth of the MAX9140/MAX9141/
MAX9142/MAX9144 requires design precautions to
realize the full high-speed capabilities of these com-
parators. The recommended precautions are:
1) Use a printed circuit board with a good, unbro-
ken, low-inductance ground plane.
2) Place a decoupling capacitor (a 0.1μF ceramic
capacitor is a good choice) as close to V
CC
as
possible.
3) Pay close attention to the decoupling capacitor
’
s
bandwidth, keeping leads short.
4) On the inputs and outputs, keep lead lengths
short to avoid unwanted parasitic feedback
around the comparators.
5) Solder the device directly to the printed circuit
board instead of using a socket.
