RH119
High Performance
Dual Comparator
DESCRIPTION
The
RH
®
119
dual comparator features low input offset
voltage and offset current, high voltage gain, guaranteed
common mode rejection and input protection diodes.
The RH119 is capable of operation over a supply range
from 5V to ±15V and can drive 25mA loads from each
open collector output. A separate GND pin allows the
RH119 to isolate system grounds.
The wafer lots are processed to Analog Devices’ in-house
Class S flow to yield circuits usable in stringent military
applications.

ELECTRICAL CHARACTERISTICS

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 for a 100mV input step with 5mV
overdrive.
Note 5:
V
S
= ±15V, V
CM
= 0V, T
A
= 25°C unless otherwise noted.
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, V
CM
= 0V
and T
A
= 25°C. The GND pin is grounded. Note that the maximum voltage
allowed between the GND pin and V
+
is 18V. Do not tie the GND 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.

PDA Test Notes
The PDA is specified as 5% based on failures from group A, subgroup
1, tests after cooldown as the final electrical test in accordance with
method 5004 of MIL-STD-883 Class B. The verified failures (including
Delta parameters) of group A, subgroup 1, after burn-in divided by the
total number of devices submitted for burn-in in that lot shall be used to
determine the percent for the lot.
Analog Devices reserves the right to test to tighter limits than those given.
