APPLICATIONS INFORMATION

U
Rail-to-Rail Input and Output
The LT1632/LT1633 are fully functional for an input and
output signal range from the negative supply to the posi-
tive supply. Figure 1 shows a simplified schematic of the
amplifier. The input stage consists of two differential
amplifiers, a PNP stage Q1/Q2 and an NPN stage Q3/Q4
that are active over different ranges of input common
mode voltage. The PNP differential input pair is active for
input common mode voltages V
CM
between the negative
supply to approximately 1.5V below the positive supply.
As V
CM
moves closer toward the positive supply, the
transistor Q5 will steer the tail current I
1
to the current
mirror Q6/Q7, activating the NPN differential pair and the
PNP pair becomes inactive for the rest of the input com-
mon mode range up to the positive supply.
The output is configured with a pair of complementary
common emitter stages Q14/Q15 that enables the output
to swing from rail to rail. These devices are fabricated on
Linear Technology’s proprietary complementary bipolar
process to ensure similar DC and AC characteristics.
Capacitors C1 and C2 form local feedback loops that lower
the output impedance at high frequencies.
Power Dissipation
The LT1632/LT1633 amplifiers combine high speed and
large output current drive in a small package. Because the

amplifiers operate over a very wide supply range, it is
possible to exceed the maximum junction temperature of
150°C in plastic packages under certain conditions. Junc-
tion temperature T
J
is calculated from the ambient tem-
perature T
A
and power dissipation P
D
as follows:
LT1632CN8: T
J
= T
A
+ (P
D
• 130°C/W)
LT1632CS8: T

= T
A
+ (P
D
• 190°C/W)
LT1633CS: T
J
= T
A
+ (P
D
• 150°C/W)
The power dissipation in the IC is the function of the supply
voltage, output voltage and load resistance. For a given
supply voltage, the worst-case power dissipation P
DMAX
occurs at the maximum supply current and when the
output voltage is at half of either supply voltage (or the
maximum swing if less than 1/2 supply voltage). There-
fore P
DMAX
is given by:
P
DMAX
= (V
S
• I
SMAX
) + (V
S
/2)
2
/R
L
To ensure that the LT1632/LT1633 are used properly,
calculate the worst-case power dissipation, use the ther-
mal resistance for a chosen package and its maximum
junction temperature to derive the maximum ambient
temperature.
Example: An LT1632CS8 operating on ±15V supplies and
driving a 500Ω, the worst-case power dissipation per
amplifier is given by:
P
DMAX
= (30V • 5.6mA) + (15V – 7.5V)(7.5/500)
= 0.168 + 0.113 = 0.281W
If both amplifiers are loaded simultaneously, then the total
power dissipation is 0.562W. The SO-8 package has a
junction-to-ambient thermal resistance of 190°C/W in still
air. Therefore, the maximum ambient temperature that the
part is allowed to operate is:
T
A
= T
J
– (P
DMAX
• 190°C/W)
T
A
= 150°C – (0.562W • 190°C/W) = 43°C
For a higher operating temperature, lower the supply
voltage or use the DIP package part.
Input Offset Voltage
The offset voltage changes depending upon which input
stage is active, and the maximum offset voltages are
trimmed to less than 1350µV. To maintain the precision
characteristics of the amplifier, the change of V
OS
over the
entire input common mode range (CMRR) is guaranteed
to be less than 1500µV on a single 5V supply.
Input Bias Current
The input bias current polarity depends on the input
common mode voltage. When the PNP differential pair is
active, the input bias currents flow out of the input pins.
