The LT1213/LT1214 will operate on any supply greater
than 2.5V and less than 36V total. These amplifiers are
specified at single 3.3V, single 5V and ±15V supplies, and
only require 2.7mA of quiescent supply current per amplifier. The inputs can be driven beyond the supplies without
damage or phase reversal of the output. The minimum
output drive is 30mA, ideal for driving low impedance
loads.

ELECTRICAL CHARACTERISTICS
Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: A heat sink may be required to keep the junction temperature
below absolute maximum when the output is shorted indefinitely.
Note 3: TJ is calculated from the ambient temperature TA and power
dissipation PD according to the following formulas:
LT1213MJ8, LT1213AMJ8: TJ = TA + (PD × 100°C/W)
LT1213CN8, LT1213ACN8: TJ = TA + (PD × 100°C/W)
LT1213CS8:
TJ = TA + (PD × 150°C/W)
LT1214CN:
TJ = TA + (PD × 70°C/W)
LT1214CS:
TJ = TA + (PD × 100°C/W)
Note 4: This parameter is not 100% tested.
Note 5: Guaranteed by correlation to 3.3V and ±15V tests.
Note 6: The LT1213/LT1214 are designed, characterized and expected to
meet these extended temperature limits, but are not tested at –40°C and
85°C. Guaranteed I grade parts are available. Consult factory.
Note 7: Slew rate is measured between ±8.5V on an output swing of ±10V
on ±15V supplies.
Note 8: Most LT1213/LT1214 electrical characteristics change very little
with supply voltage. See the 5V tables for characteristics not listed in the
3.3V table.
Note 9: Guaranteed by correlation to 5V and ±15V tests.
Note 10: Guaranteed by correlation to 3.3V tests.

Supply Voltage
The LT1213/LT1214 op amps are fully functional and all
internal bias circuits are in regulation with 2.2V of supply.
The amplifiers will continue to function with as little as
1.5V, although the input common mode range and the
phase margin are about gone. The minimum operating
supply voltage is guaranteed by the PSRR tests which are
done with the input common mode equal to 500mV and a
minimum supply voltage of 2.5V. The LT1213/LT1214 are
guaranteed over the full – 55°C to 125°C range with a
minimum supply voltage of 2.5V.
The positive supply pin of the LT1213/LT1214 should be
bypassed with a small capacitor (about 0.01µF) within an
inch of the pin. When driving heavy loads and for good
settling time, an additional 4.7µF capacitor should be
used. When using split supplies, the same is true for the
negative supply pin.
Power Dissipation
The LT1213/LT1214 amplifiers combine high speed and
large output current drive into very small packages. Because these amplifiers work over a very wide supply range,
it is possible to exceed the maximum junction temperature
under certain conditions. To insure that the LT1213/
LT1214 are used properly, calculate the worst case power
dissipation, define the maximum ambient temperature,
select the appropriate package and then calculate the
maximum junction temperature.
The worst case amplifier power dissipation is the total of
the quiescent current times the total power supply voltage
plus the power in the IC due to the load. The quiescent
supply current of the LT1213/LT1214 has a positive temperature coefficient. The maximum supply current of each
amplifier at 125°C is given by the following formula:
ISMAX = 4.2 + 0.048 × (VS – 5) in mA
VS is the total supply voltage.
The power in the IC due to the load is a function of the
output voltage, the supply voltage and load resistance. The
worst case occurs when the output voltage is at half
supply, if it can go that far, or its maximum value if it
cannot reach half supply.
For example, calculate the worst case power dissipation
while operating on ±15V supplies and driving a 500Ω load.
ISMAX = 4.2 + 0.048 × (30 – 5) = 5.4mA
PDMAX = 2 × VS × ISMAX + (VS – VOMAX) × VOMAX/RL
PDMAX = 2 × 15V × 5.4mA + (15V – 7.5V) × 7.5V/500
= 0.162 + 0.113 = 0.275 Watt per Amp
If this is the dual LT1213, the total power in the package is
twice that, or 0.550W. Now calculate how much the die
temperature will rise above the ambient. The total power
dissipation times the thermal resistance of the package
gives the amount of temperature rise. For this example, in
the SO-8 surface mount package, the thermal resistance is
150°C/W junction-to-ambient in still air.
Temperature Rise = PDMAX × θJA = 0.550W × 150°C/W
= 82.5°C
The maximum junction temperature allowed in the plastic
package is 150°C. Therefore the maximum ambient allowed is the maximum junction temperature less the
temperature rise.
Maximum Ambient = 150°C – 82.5°C = 67.5°C
That means the SO-8 dual can be operated at or below
67.5°C on ±15V supplies with a 500Ω load.
As a guideline to help in the selection of the LT1213/
LT1214, the following table describes the maximum supply voltage that can be used with each part based on the
following assumptions:
1. The maximum ambient is 70°C or 125°C depending on
the part rating.
2. The load is 500Ω including the feedback resistors.
3. The output can be anywhere between the supplies.

Inputs
Typically at room temperature, the inputs of the LT1213/
LT1214 can common mode 400mV below ground (V –)
and to within 1.2V of the positive supply with the amplifier
still functional. However, the input bias current and offset
voltage will shift as shown in the characteristic curves. For
full precision performance, the common mode range
should be limited between ground (V –) and 1.5V below the
positive supply.
When either of the inputs is taken below ground (V –) by
more than about 700mV, that input current will increase
dramatically. The current is limited by internal 100Ω
resistors between the input pins and diodes to each
supply. The output will remain low (no phase reversal) for
inputs 1.3V below ground (V –). If the output does not have
to sink current, such as in a single supply system with a 1k
load to ground, there is no phase reversal for inputs up to
8V below ground.
There are no clamps across the inputs of the LT1213/
LT1214 and therefore each input can be forced to any
voltage between the supplies. The input current will remain constant at about 100nA over most of this range.
When an input gets closer than 1.5V to the positive supply,
that input current will gradually decrease to zero until the
input goes above the supply, then it will increase due to the
previously mentioned diodes. If the inverting input is held
more positive than the noninverting input by 200mV or
more, while at the same time the noninverting input is
within 300mV of ground (V –), then the supply current will
increase by 2mA and the noninverting input current will
increase to about 10µA. This should be kept in mind in
comparator applications where the inverting input stays
above ground (V –) and the noninverting input is at or near
ground (V –).
Output
The output of the LT1213/LT1214 will swing to within
0.61V of the positive supply with no load. The open-loop
output resistance, when the output is driven hard into the
14
positive rail, is about 100Ω as the output starts to source
current; this resistance drops to about 20Ω as the current
increases. Therefore when the output sources 1mA, the
output will swing to within 0.7V of the positive supply.
While sourcing 30mA, it is within 1.25V of the positive
supply.
The output of the LT1213/LT1214 will swing to within 4mV
of the negative supply while sinking zero current. Thus, in
a typical single supply application with the load going to
ground, the output will go to within 4mV of ground. The
open-loop output resistance when the output is driven
hard into the negative rail is about 29Ω at low currents and
reduces to about 23Ω at high currents. Therefore when
the output sinks 1mA, the output is about 33mV above the
negative supply and while sinking 30mA, it is about
690mV above it.
The output of the LT1213/LT1214 has reverse-biased
diodes to each supply. If the output is forced beyond either
supply, unlimited currents will flow. If the current is
transient and limited to several hundred mA, no damage
will occur.
Feedback Components
Because the input currents of the LT1213/LT1214 are less
than 200nA, it is possible to use high value feedback
resistors to set the gain. However, care must be taken to
insure that the pole that is formed by the feedback resistors and the input capacitance does not degrade the
stability of the amplifier. For example, if a single supply,
noninverting gain of two is set with two 10k resistors, the
LT1213/LT1214 will probably oscillate. This is because
the amplifier goes open-loop at 6MHz (6dB of gain) and
has 45° of phase margin. The feedback resistors and the
10pF input capacitance generate a pole at 3MHz that
introduces 63° of phase shift at 6MHz! The solution is
simple, lower the values of the resistors or add a feedback
capacitor of 10pF or more.

Comparator Applications
Sometimes it is desirable to use an op amp as a comparator. When operating the LT1213/LT1214 on a single 3.3V
or 5V supply, the output interfaces directly with most TTL
and CMOS logic.
following photos. These amplifiers are unity-gain stable
op amps and not fast comparators, therefore, the logic
being driven may oscillate due to the long transition time.
The output can be speeded up by adding 20mV or more of
hysteresis (positive feedback), but the offset is then a
function of the input direction.
The response time of the LT1213/LT1214 is a strong
function of the amount of input overdrive as shown in the
