MAX976/MAX978/MAX998 Single/Dual/Quad, SOT23, Single-Supply, High-Speed, Low-Power Comparators ________________General Description ____________________________Features The MAX976/MAX978/MAX998 dual/quad/single, highspeed, low-power comparators are optimized for +3V/+5V single-supply applications. They achieve a 20ns propagation delay while consuming only 225µA supply current per comparator. The MAX998 features a low-power shutdown mode that places the output in a high-impedance state and reduces supply current to 1nA. The MAX976/MAX978/MAX998 inputs have a commonmode voltage range that extends 200mV below ground. Their outputs are capable of rail-to-rail operation without external pullup circuitry, making these devices ideal for interface with CMOS/TTL logic. All inputs and outputs can tolerate a continuous short-circuit fault condition to either rail. The comparators’ internal hysteresis ensures clean output switching, even with slow-moving input signals. For space-critical applications, the single MAX998 is available in a 6-pin SOT23 package, the dual MAX976 is available in an 8-pin µMAX® package, and the quad MAX978 is available in a 16-pin QSOP package. o Single-Supply Operation Down to 2.7V ________________________Applications o 20ns Propagation Delay o 225µA Supply Current o 1nA Shutdown Supply Current o Rail-to-Rail Outputs o Ground-Sensing Inputs o Internal Hysteresis Ensures Clean Switching o Available in Space-Saving Packages SOT23 (MAX998) µMAX (MAX976) QSOP (MAX978) _______________Ordering Information PART MAX976ESA+ 8 SO — MAX976EUA+ 8 µMAX — MAX978ESE+ 16 Narrrow SO — — Battery-Powered Systems Threshold Detectors/Discriminators MAX978EEE+ 16 QSOP MAX998ESA+ 8 SO 3V Systems IR Receivers MAX998EUT+T 6 SOT23 — AAAO Note: All devices are specified over the -40°C to +85°C temperature range. + Denotes a lead(Pb)-free/RoHS-compliant package.

No Connection. Not internally connected. — — 5 8 SHDN __________________Detailed Description The MAX976/MAX978/MAX998 dual/quad/single comparators operate from a single +2.7V to +5.5V supply. They achieve a 20ns propagation delay while consuming only 225µA of supply current per comparator. The MAX998 features a low-power shutdown mode that places the output in a high-impedance state and reduces supply current to 1nA. Activate shutdown mode by driving SHDN low. The MAX976/MAX978/MAX998 comparator inputs have a common-mode voltage range of -0.2V to (VCC - 1.2V). Maxim Integrated Shutdown Input. Drive low for shutdown mode. Drive high or connect to VCC for normal operation. Either input can be driven to the Absolute Maximum Ratings limit without false output inversion, as long as the other input is within the Common-Mode Voltage Range. Their push/pull output structure is capable of rail-to-rail operation without external pull-up circuitry, making these devices ideal for interfacing with CMOS/TTL logic. All inputs and outputs can tolerate a continuous short-circuit fault condition to either supply. The comparator’s internal hysteresis ensures clean output switching, even with slow-moving input signals. 5 MAX976/MAX978/MAX998 Single/Dual/Quad, SOT23, Single-Supply, High-Speed, Low-Power Comparators Hysteresis High-speed comparators can oscillate in the linear operating region because of noise or undesired parasitic feedback. This tends to occur when the voltage on one input is equal to or very close to the voltage on the other input. The MAX976/MAX978/MAX998 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 input voltages are equal, the hysteresis effectively causes one comparator input voltage to move quickly past the other, taking the input out of the region where oscillation occurs. Figure 1 illustrates the case where IN- has a fixed voltage applied and IN+ is varied. If the inputs were reversed, the figure would be the same, except with an inverted output. Input-Stage Circuitry The MAX976/MAX978/MAX998 input common-mode voltage range is from -0.2V to (VCC - 1.2V). The voltage range for each comparator input extends to both VCC and GND. The output remains in the correct logic state while one or both of the inputs are within the commonmode range. If both input levels are out of the commonmode range, input-stage current saturation occurs, and the output becomes unpredictable. Shutdown Mode The MAX998 features a low-power shutdown mode, which is activated by forcing SHDN low. Shutdown mode reduces the supply current to 1nA (typical), disables the comparator, and places the output in a highimpedance state. Drive SHDN high to enable the comparator. Do not leave SHDN unconnected. Since it is a high-impedance input, leaving SHDN unconnected could result in indeterminate logic levels, adversely VHYST VTRIP+ VIN+ VTRIP- COMPARATOR OUTPUT VOS = VTRIP+ + VTRIP2 VIN- = 0 VOH VOL Figure 1. Input and Output Waveforms, Noninverting Input Varied 6 affecting comparator operation. Likewise, do not threestate SHDN. Due to the output leakage currents of three-state devices and the small internal current for SHDN, three-stating this pin could also result in indeterminate logic levels. The maximum input voltage for SHDN is 6V, referred to GND, and is not limited by VCC. This allows the use of 5V logic to drive SHDN while VCC operates at a lower voltage, such as 3V. The logic threshold limits for SHDN are proportional to V CC (see Electrical Characteristics). _____________Applications Information Circuit Layout and Bypassing The MAX976/MAX978/MAX998 have a high-gain bandwidth and require careful board layout. We recommend the following design guidelines: 1) Use a printed circuit board with an unbroken, lowinductance ground plane. Surface-mount components are recommended. 2) Place a decoupling capacitor (a 0.1µF ceramic capacitor is a good choice) between V CC and ground as close to the pins as possible. 3) Keep lead lengths short on the inputs and outputs to avoid unwanted parasitic feedback around the comparators. 4) Solder the devices directly to the printed circuit board instead of using a socket. 5) Minimize input impedance. 6) For slowly varying inputs, use a small capacitor (~1000pF) across the inputs to improve stability. Additional Hysteresis Generate additional hysteresis with three resistors using positive feedback, as shown in Figure 2. This positive feedback method slows the hysteresis response time. Calculate resistor values as follows: 1) Select R3. The leakage current of IN+ is typically 75nA, so the current through R3 should be at least 1.0µA to minimize errors caused by leakage current. The current through R3 at the trip point is (VREF VOUT) / R3. Consider the two possible output states when solving for R3. The two formulas are: R3 = VREF/1.0µA or R3 = (VCC - VREF)/1.0µA Use the smaller of the two resulting resistor values. For example, if VREF = 1.2V and VCC = 5.0V, the two resistor values are 1.2MΩ and 3.8MΩ. Choose a standard value for R3 of 1.2MΩ. Maxim Integrated MAX976/MAX978/MAX998 Single/Dual/Quad, SOT23, Single-Supply, High-Speed, Low-Power Comparators R3 Window Comparator VCC R1 0.1µF VIN VCC R2 OUT GND VREF MAX976 MAX978 MAX998 Figure 2. Additional Hysteresis 2) Choose the hysteresis band required (VHB). For this example, choose 100mV. 3) Calculate R1. R1 = R3 x (VHB / VCC). Plugging in the values for this example, R1 = 1.2MΩ x (100mV / 5.0V) = 24kΩ 4) Choose the trip point for V IN rising. This is the threshold voltage at which the comparator switches from low to high as VIN rises above the trip point. In this example, choose 3.0V. 5) Calculate R2 as follows: R2 = R2 = 1 ⎛ VTHR ⎞ 1 1 ⎜V ⎟ − R1 − R3 ⎝ REF x R1⎠ The MAX976 is ideal for making a window detector (undervoltage/overvoltage detector). The schematic shown in Figure 3 uses a MAX6120 reference and component values selected for a 2.0V undervoltage threshold and a 2.5V overvoltage threshold. Choose different thresholds by changing the values of R1, R2, and R3. OUTA provides an active-low undervoltage indication, and OUTB gives an active-low overvoltage indication. ANDing the two outputs provides an active-high, power-good signal. The design procedure is as follows: 1) Select R1. The leakage current into INB- is normally 75nA, so the current through R1 should exceed 1.0µA for the thresholds to be accurate. R1 values in the 50kΩ to 100kΩ range are typical. 2) Choose the overvoltage threshold (VOTH) when VIN is rising, and calculate R2 and R3 with the following formula: RSUM = R2 + R3 = R1 x [VOTH / (VREF + VH) - 1] where VH = 1/2VHYST. 3) Choose the undervoltage threshold (VUTH) when VIN is falling, and calculate R2 with the following formula: R2 = (R1 + RSUM) x [(VREF - VH) / VUTH] - R1 where VH = 1/2VHYST. 4) Calculate R3 with the following formula: R3 = (RSUM) - R2 1 ⎛ 3.0V ⎞ 1 1 − ⎜ ⎟− 24kΩ 1.2M ⎝ 1.2 x 24kΩ ⎠ = 16.2kΩ 5) Verify the resistor values. The equations are as follows: VOTH = (VREF + VH) x (R1 + R2 + R3) / R1 VUTH = (VREF - VH) x (R1 + R2 + R3) / (R1 + R2) R3 82.1kΩ 1% Choose a standard value for R2 of 16kΩ. 6) Verify the trip voltage and hysteresis as follows: VIN R2 24.9kΩ 1% VCC ⎛ R1 x VCC ⎞ VIN falling : VTHF = VTHR − ⎜ ⎟ R3 ⎝ ⎠ 1 2 MAX976 2 UNDERVOLTAGE 5 7 3 1/2 The Typical Operating Circuit shows an application using the MAX998 as an infrared receiver.
