MAX9972 Quad, Ultra-Low-Power, 300Mbps ATE Drivers/Comparators General Description Features The MAX9972 four-channel, ultra-low-power, pin-elec- 2 Small FootprintFour Channels in 0.3in tronics IC includes, for each channel, a three-level pin driver, a window comparator, a passive load, and Low-Power Dissipation: 325mW/Channel (typ) force-and-sense Kelvin-switched parametric measure- High Speed: 300Mbps at 3V P-P ment unit (PMU) connections. The driver features a -2.2V to +5.2V voltage range, includes high-impedance -2.2V to +5.2V Operating Range and active-termination (3rd-level drive) modes, and is highly linear even at low voltage swings. The window Active Termination (3rd-Level Drive) comparator features 500MHz equivalent input band- Integrated PMU Switches width and programmable output voltage levels. The passive load provides pullup and pulldown voltages to Passive Load the device-under-test (DUT). Low-Leak Mode: 20nA (max) Low-leakage, high-impedance, and terminate controls are operational configurations that are programmed Low Gain and Offset Error through a 3-wire, low-voltage, CMOS-compatible serial interface. High-speed PMU switching is realized through dedicated digital control inputs.
