Part Details:

19-1569; Rev 5; 1/07 Micropower, Single-Supply, UCSP/SOT23 Comparator + Precision Reference ICs MAX9039­MAX9043/MAX9050­MAX9053 General Description Features The MAX9039­MAX9043 and MAX9050­MAX9053 fea- Comparator + Precision Reference in UCSP/SOT23 ture combinations of low-power comparators and preci- 2.5V to 5.5V Single-Supply Operation sion voltage references. Their operating voltage range (MAX9039­MAX9043) makes them ideal for both 3V and 5V systems. The Low Supply Current (MAX9039/MAX9040/ MAX9039/MAX9040/MAX9041/MAX9050/MAX9051 MAX9041/MAX9050/MAX9051) have a single comparator and reference consuming 40µA Quiescent only 40µA of supply current. The MAX9042/MAX9043/ 50µA with 100kHz Switching MAX9052/MAX9053 have dual comparators and onereference, and consume only 55µA of supply current. 400ns Propagation Delay Low-voltage operation and low supply current make Rail-to-Rail Inputs these devices ideal for battery-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 250mV beyond the supply rails. Input bias current is Voltage Reference Offers: typically 1.0pA, and input offset voltage is typically ±0.4% (max) Initial Accuracy (A grade)6ppm/°C (typ) Temperature Coefficient (A grade) 0.5mV. Internal hysteresis ensures clean output switch- Stable for 0 to 4.7nF Capacitive Loads ing, even with slow-moving input signals. The outputstage features a unique design that limits supply cur- Ordering Information rent surges while switching, virtually eliminating supplyglitches typical of many other comparators. This design PIN- TOP also minimizes overall power consumption under PART TEMP RANGE PACKAGE MARK dynamic conditions.
