LTC2053/LTC2053-SYNC
Precision, Rail-to-Rail,
Zero-Drift, Resistor-Programmable
Instrumentation Amplifier
DescripTion
FeaTures
The LTC®2053 is a high precision instrumentation ampli-
fier. The CMRR is typically 116dB with a single or dual
5V supply and is independent of gain. The input offset
voltage is guaranteed below 10µV with a temperature
drift of less than 50nV/°C. The LTC2053 is easy to use;
the gain is adjustable with two external resistors, like a
traditional op amp.

P-P
The LTC2053 uses charge balanced sampled data tech-
niques to convert a differential input voltage into a single
ended signal that is in turn amplified by a zero-drift op-
erational amplifier.

Available in MS8 and 3mm × 3mm × 0.8mm
DFN Packages
The differential inputs operate from rail-to-rail and the
single-endedoutputswingsfromrail-to-rail.TheLTC2053
can be used in single-supply applications, as low as 2.7V.
It can also be used with dual 5.5V supplies. The LTC2053
requires no external clock, while the LTC2053-SYNC has
a CLK pin to synchronize to an external clock.

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 4: The CMRR with a voltage gain, A , larger than 10 is 120dB (typ).
V
Note 5: At temperatures above 70°C, the common mode rejection ratio
lowers when the common mode input voltage is within 100mV of the
supply rails.
Note 2: These parameters are guaranteed by design. Thermocouple effects
preclude measurement of these voltage levels in high speed automatic
Note 6: The power supply rejection ratio (PSRR) measurement accuracy
depends on the proximity of the power supply bypass capacitor to the
device under test. Because of this, the PSRR is 100% tested to relaxed
limits at final test. However, their values are guaranteed by design to meet
the data sheet limits.
test systems. V is measured to a limit determined by test equipment

capability.
Note 3: If the total source resistance is less than 10k, no DC errors result
from the input bias currents or the mismatch of the input bias currents or
the mismatch of the resistances connected to –IN and +IN.

Theory of Operation
5 Volt Operation
The LTC2053 uses an internal capacitor (C ) to sample
When using the LTC2053 with supplies over 5.5V, care
must be taken to limit the maximum difference between
any of the input pins (+IN or –IN) and the REF pin to
5.5V; if not, the device will be damaged. For example, if
rail-to-rail input operation is desired when the supplies
are at 5V, the REF pin should be 0V, 0.5V. As a second
S

voltage(seetheBlockDiagram). Thiscapacitor’schargeis
transferred to a second internal hold capacitor (C ) trans-
H
lating the common mode of the input differential signal to
that of the REF pin. The resulting signal is amplified by a
zero-drift op amp in the noninverting configuration. The
RG pin is the negative input of this op amp and allows
external programmability of the DC gain. Simple filtering
can be realized by using an external capacitor across the
feedback resistor.

example, if V is 10V and V and REF are at 0V, the inputs
should not exceed 5.5V.

the input current would go to zero for DC inputs.
In reality, there are additional parasitic capacitors which
disturb the charge on C every cycle even if V is a DC
voltage. For example, the parasitic bottom plate capacitor

S
TheLTC2053hasaninternallygeneratedsampleclockthat
istypically3kHz. ThereisnoneedtoprovidetheLTC2053
with a clock. However, in some applications, it may be
desirable for the user to control the sampling frequency
more precisely to avoid undesirable aliasing. This can be
done with the LTC2053-SYNC. This device uses Pin 1 as a
clock input whereas the LTC2053 uses Pin 1 as an enable
pin. If CLK (Pin 1) is left floating on the LTC2053-SYNC,
the device will run on its internal oscillator, similar to the
LTC2053. However, if not externally synchronizing to a
system clock, it is recommended that the LTC2053 be
used instead of the LTC2053-SYNC because the LTC2053-
SYNC is sensitive to parasitic capacitance on the CLK pin
whenleftfloating. ClockingtheLTC2053-SYNCisaccom-
plished by driving the CLK pin at 8 times the desired
sample clock frequency. This completely disables the
internal clock. For example, to achieve the nominal
LTC2053sampleclockrateof3kHz,a24kHzexternalclock
to the voltage on the –IN pin every cycle. The resulting
input charging current decays exponentially during each
input sampling period with a time constant equal to R C .

If the voltage disturbance due to these currents settles
before the end of the sampling period, there will be no
errors due to source resistance or the source resistance
mismatch between –IN and +IN. With R less than 10k,
S
no DC errors occur due to this input current.
In the Typical Performance Characteristics section of this
data sheet, there are curves showing the additional error
from non-zero source resistance in the inputs. If there
are no large capacitors across the inputs, the amplifier is
less sensitive to source resistance and source resistance
mismatch. When large capacitors are placed across the
inputs, the input charging currents previously described
result in larger DC errors, especially with source resistor
mismatches.

applicaTions inForMaTion
If a square wave is used to drive the CLK pin, a 5µs RC
time constant should be placed in front of the CLK pin to
maintain low offset voltage performance (see Figure 2).
This avoids internal and external coupling of the high
frequency components of the external clock at the instant
the LTC2053-SYNC holds the sampled input.
The LTC2053-SYNC is tested with a sample clock of 3kHz
CLK
(f = 24kHz) to the same specifications as the LTC2053.
In addition, the LTC2053-SYNC is tested at one-half and
2x this frequency to verify proper operation. The curves
in the Typical Performance Characteristics section of this
data sheet apply to the LTC2053-SYNC when driving it
with a 24kHz clock at Pin 1 (f
= 24kHz, 3kHz sample

of the LTC2053-SYNC as the clock frequency is varied.
The offset is essentially unaffected over a 2:1 increase or
decrease of the typical LTC2053 sample clock speed. The
bias current is directly proportional to the clock speed.
The noise is roughly proportional to the square root of
the clock frequency. For optimum noise and bias current
performance, drive the LTC2053-SYNC with a nominal
24kHz external clock (3kHz sample clock).
