19-6350; Rev 0; 7/12 EVALUATION KIT AVAILABLE MAX9092/MAX9093/MAX9094/MAX9095 General-Purpose, Low-Voltage, Dual/Quad, Tiny Pack Comparators General Description The MAX9092/MAX9093/MAX9094/MAX9095 comparators are pin-for-pin compatible replacements for the LMX393/LMX393H/LMX339/LMX339H, respectively. The MAX9093/MAX9095 have the added benefit of internal hysteresis to provide noise immunity, preventing output oscillations even with slow-moving input signals. Advantages of the ICs include low supply voltage, small package, and low cost. They also offer a wide supply voltage range, wide operating temperature range, competitive CMRR and PSRR, response time characteristics, input offset, low noise, output saturation voltage, input bias current, and RF immunity. The ICs are available in both 8-pin SOT23/µMAXM and 14-pin TSSOP/SO packages.

The common-mode input range extends from -0.1V below the negative supply to within +0.8V of the positive supply. They require approximately 65FA per comparator with a 5V supply and 50FA with a 2.7V supply. The MAX9093/MAX9095 have 2mV of hysteresis for noise immunity. This significantly reduces the chance of output oscillations even with slow moving input signals. The ICs are ideal for automotive applications because they operate from -40NC to +125NC. See the Typical Operating Characteristics. Applications Information Hysteresis Many comparators oscillate in the linear region of operation because of noise or undesired parasitic feedback. This tends to occur when the voltage on one input is equal or very close to the voltage on the other input. The MAX9093/MAX9095 have internal hysteresis to counter parasitic effects and noise. The hysteresis in a comparator creates two trip points: one for the rising input voltage and one for the falling input voltage (Figure 1). The difference between the trip points is the hysteresis. When the comparator’s input voltages are equal, the hysteresis effectively causes one comparator input to move quickly past the other, thus taking the input out of the region where oscillation occurs. This provides clean output transitions for noisy, slow-moving input signals. 1) Find output voltage when output is high: VOUT(HIGH) = VDD - ILOAD x RL 2) Find the trip points of the comparator using these formulas: VTH = VREF + ((VOUT(HIGH) - VREF)R2)/(R1 + R2) VTL = VREF(1 - (R2/(R1 + R2))) where VTH is the threshold voltage at which the comparator switches its output from high to low as VIN rises above the trip point, and VTL is the threshold voltage at which the comparator switches its output from low to high as VIN drops below the trip point. 3) The hysteresis band is: VHYST = VTH - VTL = VDD(R2/(R1 + R2)) In this example, let VDD = 5V, VREF = 2.5V, ILOAD = 50nA, and RL = 5.1kI. VOUT(HIGH) = 5.0V - (50 x 10-9 x 5.1 x 103I) ≈ 5.0V VTH = 2.5 + 2.5(R2/(R1 + R2)) VTL = 2.5(1 - (R2/(R1 + R2))) Select R2. In this example, choose 1kI. Select VHYST. In this example, choose 50mV. Solve for R1. VHYST = VOUT(HIGH)(R2/(R1 + R2))V 0.050V = 5(1000/(R1 + 1000))V where R1 ≈ 100kI, VTH = 2.525V, and VTL = 2.475V VDD THRESHOLDS IN+ IN- Additional hysteresis can be generated with two resistors using positive feedback (Figure 2). Use the following procedure to calculate resistor values: VHYST HYSTERESIS BAND RL R1 VTH VTL R2 VREF VDD IN+ OUT VIN VOUT IN- MAX9093/MAX9095 VSS OUT Figure 1.

Adding Hysteresis with External Resistors 9 MAX9092/MAX9093/MAX9094/MAX9095 General-Purpose, Low-Voltage, Dual/Quad, Tiny Pack Comparators Chip Information Choose R1 and R2 to be large enough as not to exceed the amount of current the reference can supply. The source current required is VREF/(R1 + R2). The sink current is (VOUT(HIGH) - VREF) x (R1 + R2). Choose RL to be large enough to avoid drawing excess current, yet small enough to supply the necessary current to drive the load. RL should be between 1kI and 10kI. Choose R1 to be much larger than RL to avoid lowering VOUT(HIGH) ir raising VOUT(LOW). Board Layout and Bypassing Use 0.1FF bypass capacitors from VDD to VSS. To maximize performance, minimize stray inductance by putting this capacitor close to the VDD pin and reducing trace lengths. For slow-moving input signals (rise time > 1ms), use a 1nF capacitor between IN+ and IN- to reduce high frequency noise.
