Test Equipment Amplifiers

The LT®1466L/LT1467L are dual/quad bipolar op amps
that combine rail-to-rail input and output operation with
precision specifications. Using a patented technique,
both input stages of the LT1466L/LT1467L are trimmed:
one at the negative supply and the other at the positive
supply. The resulting common mode rejection of 83dB
minimum is much better than other rail-to-rail input op
amps. A minimum open-loop gain of 400V/mV into a 10k
load virtually eliminates all gain error. Operation is speci­fied for 3V, 5V and ±5V supplies.

Unlike other rail-to-rail amplifiers, the input offset voltage
of 390µV maximum is guaranteed across the entire rail-to-
rail input range, not just at half supply. The graph below
contrasts the VOS specifications of the LT1466L/LT1467L
to a competitive part that is specified only at half supply.
As can be seen, the LT1466L/LT1467L’s limits are much
tighter for inputs near either supply.

The LT1466L is available in 8-lead PDIP and SO-8 pack­ages with the standard dual pinout. The LT1467L features
the standard quad pinout and is available in a 16-lead
narrow SO package.

Note 1: A heat sink may be required to keep the junction temperature below

the Absolute Maximum Rating when the output is shorted indefinitely.

Note 3: Input offset match is the difference in offset voltage between
amplifiers measured at both V

Note 4: Matching parameters are the difference between amplifiers A and
D and between B and C.

APPLICATIONS INFORMATION

Rail-to-Rail Operation

The LT1466L/LT1467L differ from conventional op amps
in the design of both the input and output stages. Figure 1
shows a simplified schematic. The input stage consists of
two differential amplifiers, a PNP stage Q1-Q2 and an NPN
stage Q3-Q4, that are active over different portions of the
input common mode range. Each input stage is trimmed
for offset voltage. A complementary output configuration
(Q12-Q13) is employed to create an output stage with rail­to-rail swing. The devices are fabricated on Linear

Technology’s proprietary complementary bipolar process,
which ensures very similar DC and AC characteristics for
the output devices Q12 and Q13.

First, looking at the input stage, Q5 switches the current
from current source I1 between the two input stages.
When the input common mode voltage VCM is near the
negative supply, Q5 is reverse biased, so the current from
I1 becomes the tail current for the PNP differential pair
Q1-Q2. At the other extreme, when VCM is near the positive
supply, the PNPs Q1-Q2 are biased off. The current from

then flows through Q5 to the current mirror D3-Q6,

furnishing the tail current for the NPN differential pair
Q3-Q4. The switchover point between stages occurs when
VCM is equal to the base voltage of Q5, which is biased
approximately 1.3V below the positive supply.

The collector currents of the two input pairs are combined
in the second stage, consisting of Q7-Q11. Most of the
voltage gain in the amplifier is contained in this stage. The
output of the second stage is buffered and applied to the
output devices Q12 and Q13. Capacitors C1 and C2 form
local feedback loops around the output devices, lowering
the output impedance at high frequencies. Capacitor C
sets the amplifier bandwidth.

Input Offset Voltage

Since the amplifier has two input stages, the input offset
voltage changes depending upon which stage is active.
When the amplifier switches between stages, the offset
voltage may go up, down or remain flat. Both stages of the
LT1466L/LT1467L are trimmed; one at the negative sup-

C

ply and the other at the positive supply. The resulting
common mode rejection ratio of 83dB minimum is much
better than typical rail-to-rail amplifiers.

Overdrive Protection

The LT1466L/LT1467L contain circuits that prevent the
output from reversing polarity when the input voltage
exceeds either supply. For these circuits to work properly,
the input current should be limited to –10mA when the
input is below the negative supply, and 0.5mA when the
input is above the positive supply. If the amplifier is to be
severely overdriven, an external resistor should be used to
limit the current.

Output

The output voltage swing and current sinking capability of
the LT1466L/LT1467L are affected by input overdrive as
shown in the Typical Performance Characteristics. When
monitoring voltages within 100mV of either rail, gain
should be taken to keep the output from clipping.
