Technical content

The MAX9010/MAX9011/MAX9013 single and MAX9012 dual, high-speed comparators operate from a single 4.5V to 5.5V power supply and feature low-current con- sumption. They have precision differential inputs and TTL outputs. They feature short propagation delay (5ns, typ), low-supply current, and a wide common-mode input range that includes ground. They are ideal for low- power, high-speed, single-supply applications. The comparator outputs remain stable through the linear region when driven with slow-moving or low input-over- drive signals, eliminating the output instability common to other high-speed comparators. The input voltage range extends to 200mV below ground with no output phase reversal. The MAX9013 features complementary outputs and both the MAX9011/MAX9013 have a latch enable input (LE). The MAX9013 is an improved plug-in replacement for the industry-standard MAX913 and LT1016/LT1116, offering lower power and higher speed when used in a single 5V supply application. For space-critical designs, the single MAX9010 is avail- able in the tiny 6-pin SC70 package. The single MAX9011 is available in a space-saving 6-pin SOT23 package. The dual MAX9012 and the single MAX9013 are available in 8-pin µMAX and 8-pin SO packages. All products in the family are guaranteed over the extended temperature range of -40°C to +85°C.

Note 2: Quiescent Power-Supply Current is slightly higher with the comparator output at VOL. This parameter is specified with the worst- case condition of VOUT = VOL for the MAX9010/MAX9011 and both outputs at VOL for the MAX9012. For the MAX9013, which has complementary outputs, the power-supply current is specified with either OUT = VOL, OUT = VOH or OUT = VOH, OUT = VOL (power-supply current is equal in either case). Note 3: Input Offset Voltage is tested and specified with the Input Common-Mode Voltage set to either extreme of the Input Common- Mode Voltage Range (-0.2V to (VCC - 1.9V)) and with the Power-Supply Voltage set to either extreme of the Power-Supply Voltage Range (4.5V to 5.5V).

MAX9010–MAX9013 SC70, 5ns, Low-Power, Single-Supply, Precision TTL Comparators Note 4: Although Common-Mode Input Voltage Range is restricted to -0.2V ≤ VCM ≤ (VCC - 1.9V), either or both inputs can go to either logic decision provided that at least one of the two inputs is within the specified common-mode range. If both inputs are outside the common-mode range, the comparator output state is indeterminate. Note 5: For the MAX9012, Input Offset Voltage is defined as the input voltage(s) required to make the OUT output voltage(s) remain stable at 1.4V. For the MAX9013, it is defined as the average of two input offset voltages, measured by forcing first the OUT output, then the OUT output to 1.4V. Note 6: Propagation delay for these high-speed comparators is guaranteed by design because it cannot be accurately measured with low levels of input overdrive voltage using automatic test equipment in production. Note that for low overdrive conditions, VOS is added to the overdrive. Note 7: Differential Propagation Delay, measured either on a single output of the MAX9012/MAX9013 (or between OUT and OUT outputs on the MAX9013) is defined as: ∆tPD(±) = |(tPD+) - (tPD-)|. Note 8: Latch times are guaranteed by design. Latch setup time (tSU) is the interval in which the input signal must be stable prior to asserting the latch signal. The hold time (tH) is the interval after the latch is asserted in which the input signal must remain stable. Latch propagation delay (tLPD) is the delay time for the output to respond when the latch enable pin is deasserted (see Figure 1). t = 5ns/div RESPONSE TO -5mV OVERDRIVE IN: 50mV/div OUT: 1V/div IN +100mV MAX9010–13 toc02 OUT 6.0 3.5 1 10 100 4.0 MAX9010–13 toc03 OVERDRIVE (mV) PROPAGATION DELAY (ns) 4.5 5.0 5.5 PROPAGATION DELAY vs. INPUT OVERDRIVE 3.0 tPD(+) tPD(-) t = 5ns/div RESPONSE TO +5mV OVERDRIVE IN: 50mV/div OUT: 1V/div IN -100mV MAX9010–13 toc01 OUT Typical Operating Characteristics (VCC = 5V, CL = 15pF, TA = +25°C, unless otherwise noted.)

MAX9010–MAX9013 SC70, 5ns, Low-Power, Single-Supply, Precision TTL Comparators Detailed Description These high-speed comparators have a unique design that prevents oscillation when the comparator is in its linear region, so no minimum input slew rate is required. Many high-speed comparators oscillate in their linear region. One common way to overcome this oscillation is to add hysteresis, but it results in a loss of resolution and bandwidth. Latch Function The MAX9011/MAX9013 provide a TTL-compatible latch function that holds the comparator output state (Figure 1). With LE driven to a TTL low or grounded, the latch is transparent and the output state is determined by the input differential voltage. When LE is driven to a TTL high, the existing output state is latched, and the input differen- tial voltage has no further effect on the output state. Input Amplifier A comparator can be thought of as having two sec- tions: an input amplifier and a logic interface. The input amplifiers of these devices are fully differential, with input offset voltages typically 0.7mV at +25 ° C. Input common-mode range extends from 200mV below ground to 1.9V below the positive power-supply rail. The total common-mode range is 3.3V when operating from a 5V supply. The amplifiers have no built-in hysteresis. For highest accuracy, do not add hysteresis. Figure 2 shows how hysteresis degrades resolution. Input Voltage Range Although the common-mode input voltage range is restricted to -0.2V to (V CC - 1.9V), either or both inputs can go to either absolute maximum voltage limit, i.e., from -0.3V to (V CC + 0.3V), without damage. The com- parator will make a correct (and fast) logic decision provided that at least one of the two inputs is within the specified common-mode range. If both inputs are out- side the common-mode range, the comparator output state is indeterminate. Resolution A comparator ’s ability to resolve a small-signal differ- ence, its resolution, is affected by various factors. As with most amplifiers and comparators, the most signifi- cant factors are the input offset voltage (V OS) and the common-mode and power-supply rejection ratios (CMRR, PSRR). If source impedance is high, input off- set current can be significant. If source impedance is unbalanced, the input bias current can introduce another error.
