Detailed Description
The MAX912 (dual) and MAX913 (single) high-speed
comparators have a unique design that prevents oscil-
lation when the comparator is in its linear region. No
minimum input slew rate is required.
Many high-speed comparators oscillate in the linear
region, as shown in the Typical Operating Characteris-
tics’ industry-standard 686 response graph. One way
to overcome this oscillation is to sample the output after
it has passed through the unstable region. Another
practical solution is to add hysteresis. Either solution
results in a loss of resolution and bandwidth.
Because the MAX912/MAX913 do not need hysteresis,
they offer high resolution to all signals—including low-
frequency signals.
The MAX912/MAX913 provide a TTL-compatible latch
function that holds the comparator output state (Figure 1).
As long as Latch Enable (LE) is high or floating, the input
signal has no effect on the output state. With LE low, the
outputs are controlled by the input differential voltage
and the latch is transparent.
Input Amplifier
A comparator can be thought of as having two sec-
tions; an input amplifier and a logic interface. The
MAX912/MAX913’s input amplifier is fully differential
with input offset voltage trimmed to below 2.0mV at
+25°C. Input common-mode range extends from
200mV below the negative supply rail to 1.5V below
the positive power supply. The total common-mode
range is 8.7V when operating from ±5VDC supplies.
The MAX912/MAX913’s amplifier has no built-in hys-
teresis. For highest accuracy, do not add hysteresis.
Figure 2 shows how hysteresis degrades resolution.
Resolution
A comparator’s ability to resolve small signal differ-
ences—its resolution—is affected by various factors.
As with most amplifiers, the most significant factors are
the input offset voltage (VOS) and the common-mode
and power-supply rejection ratios (CMRR, PSRR). If
source impedance is high, input offset current can be
significant. If source impedance is unbalanced, the
input bias current can introduce another error.
For high-speed comparators, an additional factor in
resolution is the comparator’s stability in its linear
region. Many high-speed comparators are useless in
their linear region because they oscillate. This makes
the differential input voltage region around 0V unus-
able, as does a high VOS. Hysteresis does not cure the
problem, but acts to keep the input away from its linear
range (Figure 2).
The MAX912/MAX913 do not oscillate in the linear
region, which greatly enhances the comparator’s reso-
lution.
