Quad, Ultra-Low-Power, 300Mbps ATE
Drivers/Comparators
General Description
The MAX9971/MAX9972 four-channel, ultra-low-power,
pin-electronics ICs include, for each channel, a three-
level pin driver, a window comparator, a passive load,
and force-and-sense Kelvin-switched parametric mea-
surement 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).
Two grade versions are available, A grade and B grade.
The A-grade version provides tight gain and offset match-
ing for the driver and comparator, allowing reference lev-
els to be shared across multiple channels. It also
provides tighter tolerance of the load resistance values.
The B-grade version is for system designs that incorpo-
rate independent reference levels for each channel.
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.
These devices are available in an 80-pin, 12mm x 12mm
body, 1.0mm pitch TQFP with an exposed 6mm x 6mm
die pad on the bottom of the package (MAX9972), and
the top of the package (MAX9971), for efficient heat
removal. The MAX9971/MAX9972 are specified to oper-
ate over the 0°C to +70°C commercial temperature
range, and feature a die temperature monitor output.
