Single Supply Operation:  
The LT1413 is a low cost, upgraded version of Linear  
Technology’s industry standard LT1013 dual, single sup-  
ply op amp. The LT1413 is optimized for single 5V appli-  
cations, although ±15V specifications are also provided  
for completeness.  
Input Goes Below Ground  
Output Swings to Ground Sinking Current  
No Pull-Down Resistors Needed  
Phase Reversal Protection  
At 5V, 0V Low Cost Grade Specifications:  
In the design of the LT1413, particular emphasis has been  
placedonlowcostplasticandSO-8packageperformance:  
60µV offset voltage, 0.1nA offset current, in excess of  
10mA output current at 330µA supply current and 140dB  
channelseparationaresomeofthespecificationsachieved.  
280µV Max Offset Voltage  
380µV Max in S8 Package  
0.8nA Max Offset Current  
480µA Max Supply Current per Amplifier  
0.5µV/°C Drift  
1.4 Million Voltage Gain  
Other dual, single supply amplifiers are available to  
complementtheLT1413family:themicropowerLT1078’s  
supply current is 10 times lower with a 4.5 fold speed  
performance degradation compared to the LT1413. Con-  
versely, the LT1211, LT1213 and LT1215 duals have 4 to  
14 times higher supply current, but also 13 to 50 times  
higher speed.

Note 4: Gain-Bandwidth Product is not tested. It is inferred from the slew  
rate measurement.  
The  
denotes specifications which apply over the full operating  
temperature range.  
Note 5: This parameter is not 100% tested.  
Note 6: At the minimum supply voltage, the offset voltage changes less  
than 200µV compared to its value at 5V, 0V.  
Note 1: Typical parameters are defined as the 60% yield of parameter  
distributions of individual amplifiers; i.e., out of 100 LT1413s typically 120  
op amps will be better than the indicated specification.  
Note 2: This parameter is tested on a sample basis only. All noise  
parameters are tested with V = ±2.5V, V = 0V.  
Note 3: This parameter is guaranteed by design and is not tested.  
Note 7: The LT1413 is not tested and is not quality-assurance sampled at  
40°C and at 85°C. These specifications are guaranteed by design,  
correlation and/or inference from 0°C, 25°C and/or 70°C tests.

APPLICATIONS INFORMATION  
Single Supply Operation  
other amplifier out of negative saturation for the phase  
reversal protection to function properly.  
The LT1413 is fully specified for single supply operation,  
i.e., when the negative supply is 0V. Input common-mode  
range includes ground; the output swings within a few  
millivolts of ground.  
Since the output of the LT1413 cannot go exactly to  
ground, but can only approach ground to within a few  
millivolts, care should be exercised to ensure that the  
output is not saturated. For example, a 1mV input signal  
will cause the amplifier to set up in its linear region  
in the gain 100 configuration shown below, but is not  
enough to make the amplifier function properly in the  
voltage-follower mode.  
If the input is more than a few hundred millivolts below  
ground, two distinct problems can occur on previous  
single supply designs, such as the LM124, LM158, OP-21  
and OP-221.  
a) When the input is more than a diode drop below  
ground, unlimited current will flow from the substrate  
(Vterminal) to the input. This can destroy the unit. On  
the LT1413, the 400resistors, in series with the input  
(see Schematic Diagram), protect the devices even when  
the input is 5V below ground.

b) When the input is more than 400mV below ground  
(at 25°C), the input stage saturates (transistors Q3 and  
Q4) and phase reversal occurs at the output. This can  
cause lock-up in servo systems. Due to a unique phase  
reversal protection circuitry (Q21, Q22, Q27, Q28), the  
LT1413 outputs do not reverse, as illustrated below,  
even when the inputs are at –1.5V. Keep the output of the  
Figure 1.  
Comparator Applications  
The single supply operation of the LT1413 lends itself to  
its use as a precision comparator with TTL compatible  
output; the response time is shown below.
