FEATURES
DESCRIPTIO
■
The LT®6000/LT6001/LT6002 are single, dual and quad
precision rail-to-rail input and output operational amplifiers. Designed to maximize battery life in always-on applications, the devices will operate on supplies down to 1.8V
while drawing only 13µA quiescient current. The low
supply current and low voltage operation is combined with
precision specifications; input offset is guaranteed less
than 600µV. The performance on 1.8V supplies is fully
specified and guaranteed over temperature. A shutdown
feature available in the LT6000 and the 10-lead dual
LT6001 version can be used to extend battery life by
allowing the amplifiers to be switched off during periods
of inactivity.

The LT6000 is available in a tiny, dual fine pitch leadless
DFN package. The LT6001 is available in the 8-pin MSOP
package; a 10-lead version with the shutdown feature is
available in DFN package. The quad LT6002 is available in
the 16-pin SSOP package and the 16-pin DFN package.
These devices are specified over the commercial and
industrial temperature range.

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.
Note 2: A heat sink may be required to keep the junction temperature
below the absolute maximum. This depends on the power supply voltage
and how many amplifiers are shorted. The θJA specified for the DD and
DHC packages is with minimal PCB heat spreading metal. Using expanded
metal area on all layers of a board reduces this value.
Note 3: The LT6000C/LT6000I/LT6001C/LT6001I and LT6002C/LT6002I
are guaranteed functional over the temperature range of –40°C to 85°C.
Note 4: The LT6000C/LT6001C/LT6002C is guaranteed to meet specified
performance from 0°C to 70°C. The LT6000C/LT6001C/LT6002C are
designed, characterized and expected to meet specified performance from

–40°C to 85°C but are not tested or QA sampled at these temperatures.
The LT6000I/LT6001I/ LT6002I is guaranteed to meet specified
performance from –40°C to 85°C.
Note 5: This parameter is not 100% tested.
Note 6: Output voltage swings are measured between the output and
power supply rails.
Note 7: Specifications apply to the LT6000 or the LT6001DD with
shutdown.
Note 8: Guaranteed by correlation to slew rate at VS = 1.8V and GBW at
VS = 5V.
Note 9: Full-power bandwidth is calculated from the slew rate:
FPBW = SR/πVP-P.

APPLICATIO S I FOR ATIO
Supply Voltage
The positive supply of the LT6000/LT6001/LT6002 should
be bypassed with a small capacitor (about 0.01µF) within
an inch of the pin. When driving heavy loads, an additional
4.7µF electrolytic capacitor should be used. When using
split supplies, the same is true for the negative supply pin.
Rail-to-Rail Characteristics
The LT6000/LT6001/LT6002 are fully functional for an
input signal range from the negative supply to the positive
supply. Figure 1 shows a simplified schematic of the
amplifier. The input stage consists of two differential
amplifiers, a PNP stage Q3/Q6 and an NPN stage Q4/Q5
that are active over different ranges of the input common
mode voltage. The PNP stage is active for common mode
voltages, VCM, between the negative supply to approximately 1V below the positive supply. As VCM moves closer
towards the positive supply, the transistor Q7 will steer
Q2’s tail current to the current mirror Q8/Q9, activating the
NPN differential pair. The PNP pair becomes inactive for
the rest of the input common mode range up to the
positive supply.
The second stage is a folded cascode and current mirror
that converts the input stage differential signals into a
single ended output. Capacitor C1 reduces the unity cross
frequency and improves the frequency stability without
degrading the gain bandwidth of the amplifier. The complementary drive generator supplies current to the output
transistors that swing from rail to rail.
Input
The input bias current depends on which stage is active.
The input bias current polarity depends on the input
common mode voltage. When the PNP stage is active, the
input bias currents flow out of the input pins. They flow in
the opposite direction when the NPN stage is active. The
offset error due to the input bias currents can be
minimized by equalizing the noninverting and inverting
source impedance.

APPLICATIO S I FOR ATIO
Start-Up and Output Saturation Characteristics
The input offset voltage changes depending on which
input stage is active; input offset voltage is trimmed on
both input stages, and is guaranteed to be 600µV max in
the PNP stage. By trimming the input offset voltage of
both input stages, the input offset voltage over the entire
common mode range (CMRR) is typically 400µV, maintaining the precision characteristics of the amplifier.
Micropower op amps are often not micropower during
start-up characteristics or during output saturation. This
can wreak havoc on limited current supplies, in the worst
case there may not be enough supply current available to
take the system up to nominal voltages. Also, when the
output saturates, the part may draw excessive current and
pull down the supplies, compromising rail-to-rail performance. Figure 1 shows the start-up characteristics of the
LT6000/LT6001/LT6002 for three limiting cases. The circuits are shown in Figure 2. One circuit creates a positive
offset forcing the output to come up saturated high.
Another circuit creates a negative offset forcing the output
to come up saturated low, while the last circuit brings the
output up at 1/2 supply. In all cases, the supply current is
well controlled and is not excessive when the output is on
either rail.
The input stage of the LT6000/LT6001/LT6002 incorporates phase reversal protection to prevent wrong polarity
outputs from occurring when the inputs are driven up to
2V below the negative rail. 30k protective resistors are
included in the input leads so that current does not
become excessive when the inputs are forced below V– or
when a large differential signal is applied. Input current
should be limited to 10mA when the inputs are driven
above the positive rail.
Output

SUPPLY CURRENT PER AMPLIFIER (µA)
The output of the LT6000/LT6001/LT6002 can swing to
within 30mV of the positive rail with no load and within
30mV of the negative rail with no load. When monitoring
input voltages within 30mV of the positive rail or within
30mV of the negative rail, gain should be taken to keep
the output from clipping. The LT6000/LT6001/LT6002
can typically source 10mA on a single 5V supply, sourcing current is reduced to 4mA on a single 1.8V supply as
noted in the electrical characteristics.

The LT6000/LT6001/LT6002 outputs can swing to within
a respectable 30mV of each rail and draw virtually no
excessive supply current. Figure 3 compares the dual
LT6001 to a competitive part. Both op amps are in unity
gain and their outputs are driven into each rail. The supply
current is shown when the op amps are in linear operation
and when they are driven into each rail. As can be seen
from Figure 3, the supply current of the competitive part
increases 3-fold or 5-fold depending on which rail the
output goes to whereas the LT6001 draws virtually no
excessive current.

Gain
The open-loop gain is almost independent of load when
the output is sourcing current. This optimizes performance in single supply applications where the load is
returned to ground. The typical performance curve of
Open-Loop Gain for various loads shows the details.
Shutdown
The single LT6000 and the 10-lead dual LT6001 include a
shutdown feature that disables the part reducing quiescent current and makes the output high impedance. The
devices can be shut down by bringing the SHDN pin within
0.3V of V–. The amplifiers are guaranteed to shut down if
the SHDN pin is brought within 0.3V of V–. The exact
switchover point will be a function of the supply voltage.
See the Typical Performance Characteristics curves Supply Current vs Shutdown Pin Voltage. When shut down the
total supply current is about 0.8µA and the output leakage
current is 20nA (V– ≤ VOUT ≤ V+). For normal operation the
SHDN pin should be tied to V+. It can be left floating,
however, parasitic leakage currents over 1µA at the SHDN
pin may inadvertently place the part into shutdown.
