6 / 8 page +1.0V Micropower SOT23 Comparators 6 _______________________________________________________________________________________ Detailed Description The MAX9100/MAX9101 are low-power and ultra-low single-supply voltage comparators. They have an oper- ating supply voltage range between +1.0V to +5.5V and consume only 5µA of quiescent supply current, while achieving 4µs propagation delay. Input Stage Circuitry and Rail-to-Rail Operation The devices’ input common-mode range is fully speci- fied from 0 to (VCC - 0.2V), although full rail-to-rail input range is possible with degraded performance. These comparators may operate at any differential input volt- age within these limits. Input bias current is typically ±5nA if the input voltage is within the specified com- mon-mode range. Comparator inputs are protected from overvoltage by internal diodes connected to the supply rails. As the input voltage exceeds the supply rails, these diodes become forward biased and begin to conduct. Consequently, bias currents increase expo- nentially as the input voltage exceeds the supply rails. True rail-to-rail input operation is also possible. For input common-mode voltages from VCC - 0.2V to VCC, the input bias current will typically increase to 800nA. Additionally, the supply current will typically increase to 7µA. Otherwise, the device functions as within the specified common-mode range. See graphs in the Typical Operating Characteristics. Output Stage Circuitry The MAX9100/MAX9101 contain a unique output stage capable of rail-to-rail operation. Many comparators consume orders of magnitude more current during switching than during steady-state operation. However, with this family of comparators, the supply-current change during an output transition is extremely small. The Typical Operating Characteristics graph Supply Current vs. Output Transition Frequency shows the min- imal supply-current increase as the output switching frequency approaches 100kHz. This characteristic reduces the requirement for power-supply filter capaci- tors to reduce glitches created by comparator switch- ing currents. This feature increases battery life in portable applications. Push-Pull Output (MAX9100) The MAX9100 has a push-pull CMOS output. The out- put stage swings rail-to-rail under no-load conditions. External load drive capability varies with supply voltage.
