General Description
The MAX9972 four-channel, ultra-low-power, pin-elec-
tronics IC includes, for each channel, a three-level pin
driver, a window comparator, a passive load, and
force-and-sense Kelvin-switched parametric measure-
ment unit (PMU) connections. The driver features a
-2.2V to +5.2V voltage range, includes high-impedance
and active-termination (3rd-level drive) modes, and is
highly linear even at low voltage swings. The window
comparator features 500MHz equivalent input band-
width and programmable output voltage levels. The
passive load provides pullup and pulldown voltages to
the device-under-test (DUT).
Low-leakage, high-impedance, and terminate controls
are operational configurations that are programmed
through a 3-wire, low-voltage, CMOS-compatible serial
interface. High-speed PMU switching is realized through
dedicated digital control inputs.
This device is available in an 80-pin, 12mm x 12mm
body, 0.50mm pitch TQFP with an exposed 6mm x 6mm
die pad on the bottom of the package for efficient heat
removal. The MAX9972 is specified to operate over the
0°C to +70°C commercial temperature range, and fea-
tures a die temperature monitor output.
