Description
Click here to ask an associate for production status of specific part numbers. Micropower, Single-Supply, UCSP/SOT23 Comparator + Precision Reference ICs MAX9038–MAX9043/ MAX9050–MAX9053 General Description Features The MAX9038–MAX9043 and MAX9050–MAX9053 feature combinations of low-power comparators and precision voltage references. Their ope
More View rating voltage range makes them ideal for both 3V and 5V systems. The MAX9038/ MAX9039/MAX9040/MAX9041/MAX9050/MAX9051 have a single comparator and reference consuming only 40μA of supply current. The MAX9042/MAX9043/ MAX9052/MAX9053 have dual comparators and one reference, and consume only 55μA of supply current. Low-voltage operation and low supply current make these devices ideal for battery-operated systems. The comparators 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 features a unique design that limits supply current surges while switching, virtually eliminating supply glitches typical of many other comparators. This design also minimizes overall power consumption under dynamic conditions. The comparator outputs have railto-rail, push-pull output stages except the MAX9038 has an open-drain output that sinks and sources up to 8mA. The propagation delay is 400ns, even with the low-operating supply current. ● Comparator + Precision Reference in UCSP/SOT23 ● 2.5V to 5.5V Single-Supply Operation (MAX9038–MAX9043) ● Low Supply Current (MAX9038/MAX9039/MAX9040/ MAX9041/MAX9050/MAX9051) • 40μA Quiescent • 50μA with 100kHz Switching • Open-Drain Output MAX9038 ● 400ns Propagation Delay ● Rail-to-Rail Inputs ● Rail-to-Rail Output Stage Sinks and Sources 8mA ● Internal ±3mV Hysteresis ● Voltage Reference Offers • ±0.4% (max) Initial Accuracy (A Grade) • 6ppm/°C (typ) Temperature Coefficient (A Grade) • Stable for 0 to 4.7nF Capacitive Loads Ordering Information PART MAX9038BABT+T MAX9039BEBT+T MAX9039BEBT+T10 MAX9040AEUK+T MAX9040BEUK+T TEMP RANGE -40°C to +125°C -40°C to +85°C -40°C to +85°C -40°C to +85°C -40°C to +85°C PINPACKAGE 6 UCSP 6 UCSP 6 UCSP 5 SOT23 5 SOT23 TOP MARK ADW AAZ AAZ ADNV ADNX The reference output voltage is set to 1.23V in the MAX9038/ MAX9039, to 2.048V in the MAX9040–MAX9043, and to 2.500V in the MAX9050–MAX9053. The MAX9040– MAX9043 and the MAX9050–MAX9053 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 (except MAX9038/MAX9039 have an initial accuracy of ±0.4%) and 100ppm/°C tempco. The voltage references feature a proprietary curvature-correction circuit and laser-trimmed thin-film resisto
