TheLT®6015/LT6016/LT6017aresingle/dual/quadrail-to-
rail input operational amplifiers with input offset voltage
trimmed to less than 50µV. These amplifiers operate on
single and split supplies with a total voltage of 3V to 50V
and draw only 315µA per amplifier. They are reverse
battery protected, drawing very little current for reverse
supplies up to 50V.

The Over-The-Top® input stage of the LT6015/LT6016/
LT6017 is designed to provide added protection in tough
environments. The input common mode range extends

inputs up to 76V above V independent of V . Internal
resistors protect the inputs against transient faults up
to 25V below the negative supply. The LT6015/LT6016/
LT6017 can drive loads up to 25mA and are unity-gain
stable with capacitive loads as large as 200pF. Optional
external compensation can be added to extend the capaci-
tive drive capability beyond 200pF.

Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
The LT6015MP/LT6016MP/LT6017MP are guaranteed functional over the
junction temperature range of –55°C to 150°C. Junction temperatures greater
than 125°C will promote accelerated aging. The LT6015/LT6016/LT6017 has a
demonstrated typical performance beyond 1000 hours at T = 150°C.

Note 2: Voltages applied are with respect to V . The inputs are tested to
Note 5: The LT6015I/LT6016I/LT6017I are guaranteed to meet specified
performance from –40°C to 85°C. The LT6015H/LT6016H/LT6017H are
guaranteed to meet specified performance from –40°C to 125°C. The
LT6015MP/LT6016MP/LT6017MP are guaranteed to meet specified

–
the Absolute Maximum Rating by applying –25V (relative to V ) to each
input for 10ms. In general, faults capable of sinking current from either
input should be current limited to under 10mA. See the Applications
Information section for more details.
Note 3: A heat sink may be required to keep the junction temperature
below absolute maximum. This depends on the power supply voltage and
how many amplifiers are shorted.
Note 6: Test accuracy is limited by high speed test equipment repeatability. Bench
measurements indicate the input offset current in the Over-The-Top configuration
is typically controlled to under 50nA at 25°C and 150nA over temperature.
Note 4: The LT6015I/LT6016I/LT6017I are guaranteed functional over the oper-
ating temperature range of –40°C to 85°C. The LT6015H/LT6016H/LT6017H are
guaranteed functional over the operating temperature range of –40°C to 125°C.
Note 7: The Reverse Supply voltage is tested by pulling 25μA/Amplifier out

of the V pin while measuring the V pin’s voltage with both inputs and V

grounded, verifying V < –50V.

Even though the Over-The-Top input bias currents run

There are no clamping diodes between the inputs. The

However, depending on the configuration of the feedback
around the amplifier, this input resistance can boost noise
gain, lower overall amplifier loop gain and closed loop
bandwidth, raise output noise, with one benevolent effect
in increasing amplifier stability.

There are two main contributors of distortion in op amps:
output crossover distortion as the output transitions
from sourcing to sinking current and distortion caused
by nonlinear common mode rejection. If the op amp is
operating in an inverting configuration there is no com-
mon mode induced distortion. If the op amp is operating
in the noninverting configuration within the normal input
