APPLICATIONS
■
■
■
The LT119A is capable of operation over a supply range
from 5V to ±15V and can drive 25mA loads from each open
collector output. A separate ground pin allows the LT119A
to isolate system grounds.
Linear Technology Corporation’s advanced processing,
design techniques and reliability make the LT119A/LT319A
an ideal choice over previous devices in most comparator
applications.

■
The LT119A is an improved version of the LM119 dual
comparator. It features lower input offset voltage and
offset current, higher voltage gain, guaranteed common
mode rejection, and input protection diodes.

The ● denotes specifications which apply over the full operating
temperature range.
Note 1: For supply voltages less than ±15V, the maximum input voltage is
equal to the supply voltage.
Note 2: Unless otherwise noted, supply voltage equals ±15V and
TA = 25°C. The ground pin is grounded. Note that the maximum voltage
allowed between the ground pin and V + is 18V. Do not tie the ground pin
to V – when the power supply voltage exceeds ±9V. The offset voltage,
offset current and bias current specifications apply for all supply voltages
between ±15V and 5V unless otherwise specified.

Note 3: The offset voltages and currents given are the maximum values
required to drive the output within 1V of either supply with a 1mA load,
thus these parameters define an error band and take into account the
worst case effects of voltage gain and input impedance.
Note 4: Response time specified is for a 100mV input step with 5mV
overdrive.
Note 5: Inputs are protected with back-to-back 5.6V zener diodes. This
limits maximum differential input voltage to ±5V if current is unlimited.
Larger differential input drive is allowed if input current is limited to ±5mA
with external resistance.
