GENERAL DESCRIPTION
The ADCMP606 and ADCMP607 are very fast comparators
fabricated on XFCB2, an Analog Devices, Inc. proprietary
process. These comparators are exceptionally versatile and easy
to use. Features include an input range from V
V
TTL-/CMOS-compatible latch inputs with adjustable hysteresis
and/or shutdown inputs.
The devices offer 1.25 ns propagation delay with 2.5 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 +2.7 V
input signal range up to a +5.5 V positive supply with a −0.5 V

to +5.7 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
swing 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, 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 LFCSP package.
