AC Electrical Characteristics
(Continued)
Note 5:
For operation at elevated temperature, these devices must be derated based on a thermal resistance of
θ
and T
max, T
= T
+
θ
P
.
θ
for the
LM6125H and LM6225H is 17C/W. The thermal impedance
θ
of the device in the N package is 40C/W when soldered directly to a printed circuit board, and the
heat-sinking pins (pins 3, 4, 5, 10, 11, and 12) are connected to 2 square inches of 2 oz. copper. When installed in a socket, the thermal impedance
θ
JA
of the N pack-
age is 60C/W.
Note 6:
Limits are guaranteed by testing or correlation.
Note 7:
The input is biased to +2.5V, and V
IN
swings V
PP
about this value. The input swing is 2 V
PP
at all temperatures except for the A
V
3 test at 55C where it
is reduced to 1.5 V
PP
.
Note 8:
The Error Flag is set (low) during current limit or thermal fault detection in addition to being set by the Shutdown pin. It is an open-collector output which re-
quires an external pullup resistor.
Note 9:
Slew rate is measured with a
±
11V input pulse and 50
source impedance at 25C. Since voltage gain is typically 0.9 driving a 50
load, the output swing
will be approximately
±
10V. Slew rate is calculated for transitions between
±
5V levels on both rising and falling edges.Ahigh speed measurement is done to minimize
device heating. For slew rate versus junction temperature see typical performance curves. The input pulse amplitude should be reduced to
±
10V for measurements
at temperature extremes. For accurate measurements, the input slew rate should be at least 1700 V/μs.
Note 10:
The test circuit consists of the human body model of 120 pF in series with 1500
.
Note 11:
A military RETS specification is available on request. At the time of printing, the LM6125H/883 RETS spec complied with the Boldface limits in this column.
The LM6125H/883 may also be procured as Standard Military Drawing specification
