The ADCMP606/ADCMP607 are very fast comparators
fabricated on Analog Devices’ proprietary XFCB2 process.
These comparators are exceptionally versatile and easy to use.
Features include an input range from VEE − 0.5 V to VCC + 0.5 V,
low noise CML-compatible output drivers, and TTL-/CMOS-
compatible latch inputs with adjustable hysteresis and/or
The device offers 1 ns propagation delay with 2 ps RMS random
jitter (RJ). Overdrive and slew rate dispersion are typically less
than 50 ps.
A flexible power supply scheme allows the devices to operate
with a single +2.5 V positive supply and a −0.5 V to +3.0 V
input signal range up to a +5.5 V positive supply with a −0.5 V

to +6 V input signal range. The ADCMP607 features split
input/output supplies with no sequencing restrictions to support
a wide input signal range with independent output level control
and power savings.
The CML-compatible output stage is fully back-matched for
superior performance. The comparator input stage offers robust
protection against large input overdrive, and the outputs do not
phase reverse when the valid input signal range is exceeded. On
the ADCMP607, high speed latch and programmable hysteresis
features are also provided with a unique single-pin control option.
The ADCMP606 is available in a 6-lead SC70 package, and the
ADCMP607 is available in a 12-lead LSCFP package.
