PC Board Layout Considerations
Ensure that all the MAX7300 GND connections are
used. For TQFN versions, connect the underside
exposed pad to GND. A ground plane is not necessary,
but may be useful to reduce supply impedance if the
MAX7300 outputs are to be heavily loaded. Keep the
track length from the ISET pin to the RISET resistor as
short as possible, and take the GND end of the register
either to the ground plane or directly to the GND pins.
Power-Supply Considerations
The MAX7300 operates with power-supply voltages of
2.5V to 5.5V. Bypass the power supply to GND with a
0.047F capacitor as close to the device as possible.
Add a 1F capacitor if the MAX7300 is far away from
the board’s input bulk decoupling capacitor.
