GENERAL DESCRIPTION
The ADCMP603 is a very fast comparator fabricated on
XFCB2, an Analog Devices, Inc., proprietary process. This
comparator is exceptionally versatile and easy to use. Features
include an input range from VEE − 0.5 V to VCC + 0.2 V, low noise
complementary TTL-/CMOS-compatible output drivers, latch
inputs with adjustable hysteresis and a shutdown input.
The device offers 3.5 ns propagation delay with 10 mV
overdrive on 4 mA typical supply current.
A flexible power supply scheme allows the device to operate
with a single +2.5 V positive supply and a −0.5 V to +2.8 V
input signal range up to a +5.5 V positive supply with a −0.5 V
to +5.8 V input signal range. Split input/output supplies with no
sequencing restrictions support a wide input signal range while
still allowing independent output swing control and power
savings.

The device passes 4.5 kV HBM ESD testing and the absolute
maximum ratings include current limits for all pins.
The complementary TTL-/CMOS-compatible output stage is
designed to drive up to 5 pF with full timing specs and to degrade
in a graceful and linear fashion as additional capacitance is added.
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. Latch and programmable
hysteresis features are also provided with a unique single-pin
control option.
The ADCMP603 is available in a 12-lead LFCSP.
