FEATURES
DESCRIPTIO
TheLT®1211isadual,singlesupplyprecisionopampwith
a 14MHz gain-bandwidth product and a 7V/µs slew rate.
The LT1212 is a quad version of the same amplifier. The
DC precision of the LT1211/LT1212 eliminates trims in
most systems while providing high frequency perfor-
mance not usually found in single supply amplifiers.

The LT1211/LT1212 will operate on any supply greater
than 2.5V and less than 36V total. These amplifiers are
specified on single 3.3V, single 5V and ±15V supplies, and
only require 1.3mA of quiescent supply current per ampli-
fier. The inputs can be driven beyond the supplies without
damage or phase reversal of the output. The minimum
output drive is 20mA, ideal for driving low impedance
loads.

LT1211/LT1212
ELECTRICAL CHARACTERISTICS
Note 6: The LT1211C/LT1212C are guaranteed to meet specified
performance from 0°C to 70°C and are designed, characterized and
expected to meet these extended temperature limits, but are not tested at
–40°C and 85°C. The LT1211I/LT1212I are guaranteed to meet the
extended temperature limits.
Note 7: Slew rate is measured between ±8.5V on an output swing of ±10V
on ±15V supplies.
Note 8: Most LT1211/LT1212 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.
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: T is calculated from the ambient temperature T and power
J
A
dissipation P according to the following formulas:

For example, calculate the worst case power dissipation
whileoperatingon±15Vsuppliesanddrivinga500Ωload.
Supply Voltage
The LT1211/LT1212 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 LT1211/LT1212 are
guaranteed over the full –55°C to 125°C range with a
minimum supply voltage of 2.5V.
ISMAX = 2.5 + 0.036 • (30 – 5) = 3.4mA
PDMAX = 2 • VS • ISMAX + (VS – VOMAX) • VOMAX/RL
PDMAX = 2 • 15V × 3.4mA + (15V – 7.5V) • 7.5V/500
= 0.102 + 0.113 = 0.215W per Amp
If this is the quad LT1212, the total power in the package
is four times that, or 0.860W. 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 surface mount package, the thermal
resistance is 100°C/W junction-to-ambient in still air.
The positive supply pin of the LT1211/LT1212 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.
Temperature Rise = PDMAX • θJA = 0.860W • 100°C/W
= 86°C
The maximum junction temperature allowed in the plastic
package is 150°C. Therefore the maximum ambient al-
lowed is the maximum junction temperature less the
temperature rise.
Power Dissipation
The LT1211/LT1212 amplifiers combine high speed and
large output current drive into very small packages. Be-
causetheseamplifiersworkoveraverywidesupplyrange,
itispossibletoexceedthemaximumjunctiontemperature
under certain conditions. To insure that the LT1211/
LT1212 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.
Maximum Ambient = 150°C – 86°C = 64°C
That means the SO quad can only be operated at or below
64°C on ±15V supplies with a 500Ω load.
As a guideline to help in the selection of the LT1211/
LT1212, the following table describes the maximum sup-
ply voltage that can be used with each part based on the
following assumptions:
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 LT1211/LT1212 has a positive tem-
perature coefficient. The maximum supply current of each
amplifier at 125°C is given by the following formula:
1. The maximum ambient is 70°C or 125°C depending
on the part rating.
2. The load is 500Ω, includes the feedback resistors.
3. The output can be anywhere between the supplies.

Inputs
positive rail, is about 100Ω as the output starts to source
current; this resistance drops to about 25Ω as the current
increases. Therefore when the output sources 1mA, the
output will swing to within 0.7V of the positive supply.
While sourcing 20mA, it is within 1.1V of the positive
supply.
Typically, at room temperature, the inputs of the LT1211/
LT1212 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
shouldbelimitedbetweenground(V–)and1.5Vbelowthe
positive supply.
When either of the inputs is taken below ground (V–) by
more than about 700mV, that input bias 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
inputs1.3Vbelowground(V–).Iftheoutputdoesnothave
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.
TheoutputoftheLT1211/LT1212willswingtowithin3mV
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 3mV of ground. The
open-loop output resistance when the output is driven
hardintothenegativerailisabout44Ωatlowcurrentsand
reduces to about 24Ω at high currents. Therefore, when
the output sinks 1mA, the output is about 42mV above the
negative supply and while sinking 20mA, it is about
480mV above it.
The output of the LT1211/LT1212 has reverse-biased
diodestoeachsupply. Iftheoutputisforcedbeyondeither
supply, unlimited currents will flow. If the current is
transient and limited to several hundred mA, no damage
will occur.
There are no clamps across the inputs of the LT1211/
LT1212 and therefore each input can be forced to any
voltage between the supplies. The input current will re-
main constant at about 60nA over most of this range.
Whenaninputgetscloserthan1.5Vtothepositivesupply,
that input current will gradually decrease to zero until the
inputgoesabovethesupply, thenitwillincreaseduetothe
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 1mA 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–).
Feedback Components
Because the input currents of the LT1211/LT1212 are less
than 125nA, 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 resis-
tors 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 20k resistors, the
LT1211/LT1212 will probably oscillate. This is because
the amplifier goes open-loop at 3MHz (6dB of gain) and
has 50° of phase margin. The feedback resistors and the
10pF input capacitance generate a pole at 1.6MHz that
introduces 63° of phase shift at 3MHz! The solution is
simple; use lower value resistors or add a feedback
capacitor of 10pF or more.
Output
The output of the LT1211/LT1212 will swing to within
0.60V of the positive supply with no load. The open-loop
output resistance, when the output is driven hard into the

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.
Comparator Applications
Sometimes it is desirable to use an op amp as a compara-
tor. When operating the LT1211/LT1212 on a single 3.3V
or 5V supply, the output interfaces directly with most TTL
and CMOS logic.
The response time of the LT1211/LT1212 is a strong
function of the amount of input overdrive as shown in the
