Rainbow Electronics MAX996 User Manual

________________General Description
The MAX987/MAX988/MAX991/MAX992/MAX995/ MAX996 single/dual/quad micropower comparators feature low-voltage operation and Rail-to-Rail®inputs and outputs. Their operating voltage ranges 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 48µA per comparator while achieving a 120ns 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 MAX987/MAX991/MAX995 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 MAX988/MAX992/MAX996 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 MAX987/MAX988 are available in tiny 5-pin SC70 packages, while the dual MAX991/MAX992 are available in ultra-small 8-pin SOT23 packages.

NAME FUNCTION
Detailed Description
The MAX987/MAX988/MAX991/MAX992/MAX995/ MAX996 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 48µA per comparator, while achieving 120ns propaga­tion delay. 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-to­rail 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 MAX987/MAX991/MAX995 have a push/pull output structure that sinks as well as sources current. The MAX988/MAX992/MAX996 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. Battery life increases substantially in high-speed, battery-powered applications.
Applications Information
Additional Hysteresis
MAX987/MAX991/MAX995
The MAX987/MAX991/MAX995 have ±2.5mV 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 MAX987/MAX991/MAX995.
1) Select R3. Leakage current at IN is under 10nA; therefore, 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 and 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:
MAX988/MAX992/MAX996
The MAX988/MAX992/MAX996 have ±2.5mV internal hysteresis. They have open-drain outputs and require an external pull-up resistor (Figure 2). Additional hys­teresis can be generated using positive feedback, but the formulas differ slightly from those of the MAX987/MAX991/MAX995.
Use the following procedure to calculate resistor values:
1) Select R3 according to the formulas R3 = V
REF
/ 1µA
or R3 = (V
REF
- VCC) / 1µA - R4. Use the smaller of
the two resulting resistor values.
2) Choose the hysteresis band required (VHB). For this example, choose 50mV.
3) Calculate R1 according to the following equation:
R1 = (R3 + R4) x (VHB/ VCC)
4) Choose the trip point for V
IN
rising (V
THR
; V
THF

5) Calculate R2 as follows:
6) Verify trip voltages and hysteresis as follows:
Circuit Layout and Bypassing
These comparators high-gain bandwidth requires design precautions to maximize their high-speed capa­bility. The recommended precautions are:
1) Use a printed circuit board with an unbroken, low­inductance ground plane.
2) Place a decoupling capacitor (a 0.1µF ceramic capacitor is a good choice) as close to VCCas possible.
3) On the inputs and outputs, keep lead lengths short to avoid unwanted parasitic feedback around the comparators.
4) Solder the devices directly to the printed circuit board instead of using a socket.

Zero-Crossing Detector
Figure 3 shows a zero-crossing detector application. The MAX987s inverting input is connected to ground, and its noninverting input is connected to a 100mVp-p signal source. As the signal at the noninverting input crosses 0V, the comparators output changes state.
Logic-Level Translator
Figure 4 shows an application that converts 5V logic lev­els to 3V logic levels. The MAX988 is powered by the +5V supply voltage, and the pull-up resistor for the MAX988’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 pull-up resistor.
