NJU7109
LOW POWER SUPER SMALL-SIZED
SINGLE C-MOS COMPARATOR
■GENERAL
DESCRIPTION
The
NJU7109
is super small-sized package single C-MOS
comparator with push pull output.
The operating voltage is from 1.8V to 5.5V, and the interface
can be connected with most of TTL and C-MOS type standard
logic ICs.
Furthermore, The input offset voltage is lower than 7mV and
the package is super small-sized SC88A, therefore they can be
suitable for battery use items and other portable items.

Note1) If the supply voltage (V
DD
) is less than 7.0V, the input voltage must not over the V
DD
level though 7.0V is limit
specified.
Note2) EIA/JEDEC STANDARD Test board (76.2 x 114.3 x 1.6mm, 2layers, FR-4) mounting.
Note3) Decoupling capacitor should be connected between V
DD
and V
SS
due to the stabilized operation for the circuit.
