General Description
The MAX985/MAX986/MAX989/MAX990/MAX993/ MAX994 single/dual/quad micropower comparators feature low-voltage operation and rail-to-rail inputs and outputs. Their operating voltages range from 2.5V to
5.5V, making them ideal for both 3V and 5V systems. These comparators also operate with ±1.25V to ±2.75V dual supplies. They consume only 11µA of supply cur­rent while achieving a 300ns propagation delay.
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’s unique design limits supply-current surges while switching, virtually eliminating the supply glitches typical of many other comparators. The MAX985/MAX989/MAX993 have a push-pull output stage that sinks as well as sources current. Large inter­nal output drivers allow rail-to-rail output swing with loads up to 8mA. The MAX986/MAX990/MAX994 have an open-drain output stage that can be pulled beyond VCCto 6V (max) above VEE. These open-drain versions are ideal for level translators and bipolar to single­ended converters.
The single MAX985 is available in a chip-scale pack­age (UCSP™), significantly reducing the required PC board area. The single MAX985/MAX986 are available in 5-pin SC70 packages and the dual MAX989/MAX990 are available in 8-pin SOT23 packages.

_______________Detailed Description
The MAX985/MAX986/MAX989/MAX990/MAX993/ MAX994 are single/dual/quad low-power, low-voltage comparators. They have an operating supply voltage range between 2.5V and 5.5V and consume only 11µA. Their common-mode input voltage range extends 0.25V beyond each rail. Internal hysteresis ensures clean out­put switching, even with slow-moving input signals. Large internal output drivers allow rail-to-rail output swing with up to 8mA loads.
The output stage employs a unique design that mini­mizes supply-current surges while switching, virtually eliminating the supply glitches typical of many other comparators. The MAX985/MAX989/MAX993 have a push-pull output structure that sinks as well as sources current. The MAX986/MAX990/MAX994 have an open­drain output stage that can be pulled beyond VCCto an absolute maximum of 6V above VEE.
Input Stage Circuitry
The devices’ input common-mode range extends from
-0.25V to (VCC+ 0.25V). These comparators may oper­ate at any differential input voltage within these limits. Input bias current is typically 1.0pA if the input voltage is between the supply rails. Comparator inputs are pro­tected from overvoltage by internal body diodes con­nected to the supply rails. As the input voltage exceeds the supply rails, these body diodes become forward biased and begin to conduct. Consequently, bias cur­rents increase exponentially as the input voltage exceeds the supply rails.
Output Stage Circuitry
These comparators contain a unique output stage capable of rail-to-rail operation with up to 8mA loads. 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 minimal supply-current increase as the out­put switching frequency approaches 1MHz. This char­acteristic eliminates the need for power-supply filter capacitors to reduce glitches created by comparator switching currents. Another advantage realized in high­speed, battery-powered applications is a substantial increase in battery life.
__________Applications Information
Additional Hysteresis
MAX985/MAX989/MAX993
The MAX985/MAX989/MAX993 have ±3mV internal hysteresis. Additional hysteresis can be generated with three resistors using positive feedback (Figure 1). Unfortunately, this method also slows hysteresis response time. Use the following procedure to calcu­late resistor values for the MAX985/MAX989/MAX993.
1) Select R3. Leakage current at IN is under 10nA, so the current through R3 should be at least 1µA to minimize errors caused by leakage current. The cur­rent through R3 at the trip point is (V
REF
- V
OUT
) / R3. Considering the two possible output states in solving for R3 yields two formulas: R3 = V
REF
/ 1µA
or R3 = (V
REF
- VCC) / 1µA. Use the smaller of the
two resulting resistor values. For example, if V
REF
=
1.2V and VCC= 5V, then the two R3 resistor values are 1.2Mand 3.8M. Choose a 1.2Mstandard value for R3.
2) Choose the hysteresis band required (VHB). For this example, choose 50mV.
3) Calculate R1 according to the following equation:
R1 = R3 x (VHB/ VCC)
For this example, insert the values R1 = 1.2MΩ x (50mV / 5V) = 12kΩ.
4) Choose the trip point for VINrising (V
THR
; V
THF
is the trip point for VINfalling). This is the threshold voltage at which the comparator switches its output from low to high as VINrises above the trip point. For this example, choose 3V.

6) Verify trip voltages and hysteresis as follows:
MAX986/MAX990/MAX994
The MAX986/MAX990/MAX994 have ±3mV internal hysteresis. They have open-drain outputs and require an external pullup resistor (Figure 2). Additional hys­teresis can be generated using positive feedback, but the formulas differ slightly from those of the MAX985/MAX989/MAX993.
Use the following procedure to calculate resistor values:
1) Select R3 according to the formulas R3 = V
REF
/
500µA or R3 = (V
REF
- VCC) / 500µA - R4. Use the
smaller of the two resulting resistor values.
2) Choose the hysteresis band required (V
HB
). For this
example, choose 50mV.
3) Calculate R1 according to the following equation:
R1 = (R3 + R4) x (V
HB
/ VCC)
4) Choose the trip point for V
IN
rising (V
THR
; V
THF
is the trip point for VINfalling). This is the threshold voltage at which the comparator switches its output from low to high as VINrises above the trip point.
5) Calculate R2 as follows:
6) Verify trip voltages and hysteresis as follows:
Board Layout and Bypassing
Power-supply bypass capacitors are not typically need­ed, but use 100nF bypass capacitors when supply impedance is high, when supply leads are long, or when excessive noise is expected on the supply lines. Minimize signal trace lengths to reduce stray capacitance.

Zero-Crossing Detector
Figure 3 shows a zero-crossing detector application. The MAX985’s inverting input is connected to ground, and its noninverting input is connected to a 100mV
P-P
signal source. As the signal at the noninverting input crosses 0V, the comparator’s output changes state.
Logic-Level Translator
Figure 4 shows an application that converts 5V logic lev­els to 3V logic levels. The MAX986 is powered by the 5V supply voltage, and the pullup resistor for the MAX986’s open-drain output is connected to the 3V supply voltage. This configuration allows the full 5V logic swing without creating overvoltage on the 3V logic inputs. For 3V to 5V logic-level translation, simply connect the 3V supply to VCCand the 5V supply to the pullup resistor.
