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).

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.

This device is 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 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.
