mikroElektronika Comparator click Quick Start Manual

Comparator click
1. Introduction
Comparator click, carrying the LM2903 IC, has
two independent precision voltage compara-
tors. Two pairs of screw terminals allow you
to connect separate inputs (additional two
screw terminals are for GND connections).
Two potentiometers are placed between
the terminals and the IC. Each input has its
own Interrupt pin on the mikroBUS ™ socket
(one on the INT pin, the other in place of the
mikroBUS AN pin), here marked 01 and 02.

2. Soldering the headers
Before using your click board ™ , make sure
to solder 1x8 male headers to both left and
right side of the board. Two 1x8 male headers
are included with the board in the package.

Turn the board upside down so that
the bottom side is facing you upwards.
Place shorter pins of the header into the
appropriate soldering pads.

Turn the board upward again. Make sure
to align the headers so that they are
perpendicular to the board, then solder the
pins carefully.
3. Plugging the board in
Once you have soldered the headers your
board is ready to be placed into the desired
mikroBUS socket. Make sure to align the
™
cut in the lower-right part of the board with
the markings on the silkscreen at the
mikroBUS socket. If all the
™
pins are aligned correctly,
push the board all the way
into the socket.
4. Essential features
Comparator click can be used with a single
or dual power supply. If a single power
supply is used, the offset voltage can be as
low as 2.0 mV, with a range from 2.0 VDC to
36 VDC. For dual supplies, the range is from
±1.0 VDC to ±18 VDC. The resulting output
is compatible with TTL, DTL, ECL, MOS and
CMOS logic systems.
