Optional Noise Reduction Capacitor
A noise reduction capacitance of ~1nF can be con-
nected between OUT and FB, if needed. Noise reduc-
tion is achieved by both limiting the amplifier
bandwidth, reducing contribution of broadband white
noise and by attenuating contribution of any small
20kHz autozero ripple that appears at the output. Using
higher values of feedback capacitance reduces the
output noise of the amplifier, but also reduces its signal
bandwidth.
Efficiency and Power Dissipation
At high current levels, the I2R losses in RSENSE can be
significant. Take this into consideration when choosing
the resistor value and its power dissipation (wattage)
rating. The sense resistor’s value will drift if it is allowed
to heat up excessively. The precision VOS of the
MAX9922/MAX9923 allows the use of small sense resis-
tors to reduce power dissipation and reduce hot spots.
Sense Resistor Connections
Take care to prevent solder and trace resistance from
causing errors in the sensed voltage because of the high
currents that flow through RSENSE. Either use a four termi-
nal current-sense resistor or use Kelvin (force and sense)
PCB layout techniques to minimize these errors.
