Note 1: This device is constructed using a unique set of packaging techniques that impose a limit on the thermal profile the device can be exposed to during board-level solder attach and rework. This limit permits only the use of the solder profiles recommended in the industry-standard specification, JEDEC 020A, paragraph 7.6, Table 3 for IR/VPR and Convection Packaging Reflow. Preheating is required. Hand or wave soldering is not allowed.

Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

The MAX9042 and MAX9050MAX9053 feature combinations of low-power comparators and precision voltage references. Their operating voltage range makes them ideal for both 3V and 5V systems. The MAX9039/MAX9040/MAX9041/MAX9050/MAX9051 have a single comparator and reference consuming only 40A of supply current. The MAX9042/MAX9043/MAX9052/MAX9053 have dual comparators and one reference, and consume only 55A of supply current. Low-voltage operation and low supply current make these MAX9042 ideal for battery-operated systems.

The comparators MAX9042 feature Rail-to-Rail® inputs and outputs, with a common-mode input voltage range that extends 250mV beyond the supply rails. Input bias current is typically 1.0pA, and input offset voltage is typically 0.5mV. Internal hysteresis ensures clean output switching, even with slow-moving input signals. The output stage of MAX9042 features a unique design that limits supply current surges while switching, virtually eliminating supply glitches typical of many other comparators. This design of MAX9042 also minimizes overall power consumption under dynamic conditions. The comparator outputs have rail-to-rail, push-pull output stages that sink and source up to 8mA. The propagation delay is 400ns, even with the low-operating supply current.

The reference output voltage of MAX9042 is set to 1.23V in the MAX9039, to 2.048V in the MAX9040MAX9043, and to 2.500V in the MAX9050MAX9053. The MAX9040 MAX9043 and the MAX9050MAX9053 are offered in two grades: an A grade with 0.4% initial accuracy and 6ppm/°C tempco, and a B grade with 1% initial accuracy and 100ppm/°C tempco. The voltage references of MAX9042 feature a proprietary curvature-correction circuit and laser-trimmed thin-film resistors. These series-mode references can sink or source up to 500A of load current.
