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 package.

10 Q
Inverting Output. Q is at logic low if the analog voltage at the noninverting input, VP, is greater than the analog
voltage at the inverting input, VN, if the comparator is in compare mode. See the LE/HYS pin description (Pin 8)
for more information.
11 VEE Negative Supply Voltage.
12 Q
Noninverting Output. Q is at logic high if the analog voltage at the noninverting input, VP, is greater than the
analog voltage at the inverting input, VN, if the comparator is in compare mode. See the LE pin description
(Pin 8) for more information.
Heat Sink VEE
Paddle
The metallic back surface of the package is electrically connected to VEE. It can be left floating because Pin 3, Pin 5,
Pin 9, and Pin 11 provide adequate electrical connection. It can also be soldered to the application board if
improved thermal and/or mechanical stability is desired. Exposed metal at package corners is connected to the
heat sink paddle.
