MAX9038MAX9043/ Micropower, Single-Supply, UCSP/SOT23 MAX9050MAX9053 Comparator + Precision Reference ICs General Description Features The MAX9038MAX9043 and MAX9050MAX9053 feature Comparator + Precision Reference in UCSP/SOT23 combinations of low-power comparators and precision 2.5V to 5.5V Single-Supply Operation voltage references. Their operating voltage range makes (MAX9038MAX9043) them ideal for both 3V and 5V systems. The MAX9039/ Low Supply Current (MAX9038/MAX9039/MAX9040/ MAX9040/MAX9041/MAX9050/MAX9051 have a single MAX9041/MAX9050/MAX9051) comparator and reference consuming only 40A of supply 40A Quiescent current. The MAX9042/MAX9043/MAX9052/MAX9053 50A with 100kHz Switching have dual comparators and one reference, and consume Open-Drain Output MAX9038 only 55A of supply current. Low-voltage operation and 400ns Propagation Delay low supply current make these devices ideal for battery- Rail-to-Rail Inputs operated systems. Rail-to-Rail Output Stage Sinks and Sources 8mA The comparators feature rail-to-rail inputs and outputs, Internal 3mV Hysteresis with a common-mode input voltage range that extends Voltage Reference Offers 250mV beyond the supply rails. Input bias current is 0.4% (max) Initial Accuracy (A Grade) typically 1.0pA, and input offset voltage is typically 0.5mV. 6ppm/C (typ) Temperature Coefficient (A Grade) Internal hysteresis ensures clean output switching, even Stable for 0 to 4.7nF Capacitive Loads with slow-moving input signals. The output stage features Ordering Information a unique design that limits supply current surges while PIN- TOP switching, virtually eliminating supply glitches typical of PART TEMP RANGE PACKAGE MARK many other comparators. This design also minimizes MAX9038BABT+T -40C to +125C 6 UCSP ADW overall power consumption under dynamic conditions.

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.
