MAX9632
Careful layout technique helps optimize performance
by decreasing the amount of stray capacitance at the
op amp’s inputs and outputs. To decrease stray capaci-
tance, minimize trace lengths by placing external com-
ponents close to the op amp’s pins.
For high-frequency designs, ground vias are critical to
provide a ground return path for high-frequency signals
and should be placed near the decoupling capacitors.
Signal routing should be short and direct to avoid para-
sitic effects. Avoid using right angle connectors since
they may introduce a capacitive discontinuity and ulti-
mately limit the frequency response.
Electrostatic Discharge (ESD)
The IC has built-in circuits to protect it from ESD events.
An ESD event produces a short, high-voltage pulse
that is transformed into a short current pulse once it
discharges through the device. The built-in protection
circuit provides a current path around the op amp that
prevents it from being damaged. The energy absorbed
by the protection circuit is dissipated as heat.
ESD protection is guaranteed up to Q8kV with the Human
Body Model (HBM). The Human Body Model simulates
the ESD phenomenon wherein a charged body directly
transfers its accumulated electrostatic charge to the
ESD-sensitive device. A common example of this phe-
nomenon is when a person accumulates static charge
by walking across a carpet and then transfers all of the
charge to an ESD-sensitive device by touching it.
Not all ESD events involve the transfer of charge into the
device. ESD from a charged device to another body is
also a common form of ESD.
If a charged device comes into contact with another
conductive body that is at a lower potential, it discharges
into that body. Such an ESD event is known as Charged
Device Model (CDM) ESD, which can be even more
destructive than HBM ESD (despite its shorter pulse
duration) because of its high current. The IC guarantees
CDM ESD protection up to Q1kV.
Driving High-Resolution Sigma-Delta ADCs
The MAX9632’s excellent AC specifications and 55MHz
bandwidth are a good fit for driving high-speed, precision
delta-sigma ADCs. These ADCs require an ultra-low noise
op amp to achieve signal-to-noise ratios (SNR) better than
100dB. The MAX11040 is a 24-bit, 4-channel, simultane-
ous-sampling ADC with 117dB SNR at 1ksps and 106dB
at 16ksps. The MAX11040 measures analog inputs up to
Q
2.2V. Sampling up to 64ksps, the MAX11040 achieves
better than -94dB THD and 94dB SFDR.
The MAX11040 measures four differential inputs simulta-
neously, outputting the data through an SPI interface
to allow daisy-chaining the data outputs and inputs
together. Therefore, up to eight MAX11040 devices can
be placed in parallel to measure up to 32 inputs simulta-
neously. This is ideal for 3-phase power monitoring that
requires multiple current and voltage readings and very
wide dynamic range.
The Typical Application Circuit shows an example of the
MAX9632 driving the MAX11040.
