19-2064; Rev 3; 1/10 40ns, Low-Power, 3V/5V, Rail-to-Rail Single-Supply Comparators The MAX9140/MAX9141 are single and the MAX9142/ MAX9144 are dual/quad high-speed comparators optimized for systems powered from a 3V or 5V supply. The MAX9141 features latch enable and device shutdown. These devices combine high speed, low power, and rail-to-rail inputs. Propagation delay is 40ns, while supply current is only 150µA per comparator. The input common-mode range of the MAX9140/ MAX9141/MAX9142/MAX9144 extends beyond both power-supply rails. The outputs pull to within 0.3V of either supply rail without external pullup circuitry, making these devices ideal for interface with both CMOS and TTL logic. All input and output pins can tolerate a continuous short-circuit fault condition to either rail. Internal hysteresis ensures clean output switching, even with slow-moving input signals. The MAX9140/MAX9141/MAX9142/MAX9144 are higher-speed, lower-power, and lower-cost upgrades to industry-standard comparators MAX941/MAX942/ MAX944. The MAX9140 are offered in tiny 5-pin SC70 and SOT23 packages. The MAX9141 and MAX9142 are available in 8-pin SOT23 and SO packages, while the MAX9144 is available in both 14-pin SO and TSSOP packages.

Their outputs are pulled to within 300mV of either supply rail without external pullup or pulldown circuitry. Rail-to-rail input voltage range and low-voltage single-supply operation make these devices ideal for portable equipment. The MAX9140/MAX9141/MAX9142/MAX9144 interface directly to CMOS and TTL logic. Most high-speed comparators oscillate in the linear region because of noise or undesired parasitic feedback. This tends to occur when the voltage on one input is at or equal to the voltage on the other input. To counter the parasitic effects and noise, the MAX9140/ MAX9141/MAX9142/MAX9144 have an internal hysteresis of 1.5mV. 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. The average of the trip points is the offset voltage. When the comparator’s input voltages are equal, the hysteresis effectively causes one comparator input voltage to move quickly past the other, thus taking the input out of the region where oscillation occurs. Standard comparators require hysteresis to be added with external resistors. The MAX9140/MAX9141/MAX9142/MAX9144’s fixed internal hysteresis eliminates these resistors. To increase hysteresis and noise margin even more, add positive feedback with two resistors as a voltage divider from the output to the noninverting input. Figure 1 illustrates the case where IN- is fixed and IN+ is varied. If the inputs were reversed, the figure would look the same, except the output would be inverted. The MAX9141 includes an internal latch that allows — storage of comparison results. The LE pin has a high — input impedance. If LE is high, the latch is transparent (i.e., the comparator operates as though the latch is not present). The comparator's output state is latched — when LE is pulled low (Figure 2). Shutdown Mode (MAX9141 Only) –———– The MAX9141 shuts down when the SHDN pin is low. When shut down, the supply current drops to less than 12µA, and the three-state output becomes high imped–———– ance. The S H D N pin has a high-input impedance. ———– Connect SHDN to VCC for normal operation. Exit shutdown with L—E high (transparent state); otherwise, the output will be indeterminate.

Input and Output Waveform, Noninverting Input Varied Input Stage Circuitry The MAX9140/MAX9141/MAX9142/MAX9144 include internal protection circuitry that prevents damage to the precision input stage from large differential input voltages. This protection circuitry consists of two back-toback diodes between IN+ and IN- as well as two series 4.1kΩ resistors (Figure 3). The diodes limit the differential voltage applied to the internal circuitry of the comparators to be no more than 2VF, where VF is the forward voltage drop of the diode (about 0.7V at +25°C). For a large differential input voltage (exceeding 2VF), this protection circuitry increases the input bias current at IN+ (source) and IN- (sink). Input Current = (IN+ - IN-) - 2VF 2 x 4.1kΩ Input current with large differential input voltages should not be confused with input bias current (IB). As long as the differential input voltage is less than 2VF, this input current is equal to IB. The output is in the correct logic state if one or both inputs are within the common-mode range. _______________________________________________________________________________________ 7 MAX9140/MAX9141/MAX9142/MAX9144 Detailed Description MAX9140/MAX9141/MAX9142/MAX9144 40ns, Low-Power, 3V/5V, Rail-to-Rail Single-Supply Comparators tS VOS DIFFERENTIAL INPUT VOLTAGE tH VOD tLPW VCC LE VCC 2 0 VOH OUT tPD tLPD VCC 2 VOL Figure 2. MAX9141 Timing Diagram with Latch Operator Output Stage Circuitry The MAX9140/MAX9141/MAX9142/MAX9144 contain a current-driven output stage as shown in Figure 4. During an output transition, ISOURCE or ISINK is pushed or pulled to the output pin. The output source or sink current is high during the transition, creating a rapid slew rate. Once the output voltage reaches V OH or VOL, the source or sink current decreases to a small value, capable of maintaining the VOH or VOL static condition. This significant decrease in current conserves power after an output transition has occurred. One consequence of a current-driven output stage is a linear dependence between the slew rate and the load capacitance. A heavy capacitive load will slow down a voltage output transition. This can be useful in noisesensitive applications where fast edges may cause interference. 4.1kΩ IN+ TO INTERNAL CIRCUITRY MAX9140 MAX9141 MAX9142 MAX9144 TO INTERNAL CIRCUITRY IN– 4.1kΩ Applications Information Circuit Layout and Bypassing The high-gain bandwidth of the MAX9140/MAX9141/ MAX9142/MAX9144 requires design precautions to realize the full high-speed capabilities of these comparators. The recommended precautions are: 1) Use a PCB with a good, unbroken, low-inductance ground plane. 2) Place a decoupling capacitor (a 0.1µF ceramic capacitor is a good choice) as close to VCC as possible. 8 Figure 3. Input Stage Circuitry 3) Pay close attention to the decoupling capacitor’s bandwidth, keeping leads short. 4) On the inputs and outputs, keep lead lengths short to avoid unwanted parasitic feedback around the comparators. 5) Solder the device directly to the PCB instead of using a socket. _______________________________________________________________________________________ 40ns, Low-Power, 3V/5V, Rail-to-Rail Single-Supply Comparators VCC MAX9140 MAX9141 MAX9142 MAX9144 ISOURCE VREFC SERIAL DIGITAL INPUT SDI VDD 8-BIT DAC MAX512 OUTPUT DACOUTC GND VSS MAX9140 ISINK GND ANALOG IN Figure 4.
