GENERAL DESCRIPTION
+IN
V
–IN A
The OP220 is a monolithic dual operational amplifier that can
be used either in single or dual supply operation. T he low offset
voltage and input offset voltage tracking as low as 1.0 mV/∞C,
make this the first micropower precision dual operational amplifier.

T he excellent specifications of the individual amplifiers com-
bined with the tight matching and temperature tracking between
channels provides high performance in instrumentation am
fier designs. T he individual amplifiers feature extremel
input offset voltage, low offset voltage drift, low nois
and low bias current. They are fully compensated and
Matching between channels is provided on all cical pa
including input offset voltage, tracking of set voltage ver
temperature, noninverting bias currents, d commode
rejection ratios.

INSTRUMENTATIOAPPLICATIONS OF
THE OP220
Two Op Amp Configuration
The excellent input characteristics of the OP220 make it ideal for
use in instrumentation amplifier configurations where low-level
differential signals are to be amplified. T he low-noise, low input
offsets, low drift, and high gain combined with excellent CMRR
provide the characteristics needed for high-performance instru-
mentation amplifiers. In addition, the power supply current
drain is very low.
If the instrumentation amplifier were designed for a gain of 10
and maximum VD of ±1 V, then RN/RO would need to be four
and VO would be a maximum of ±10 V. Amplifier A1 would
have a maximum output of ±5 V plus 2 VCM, thus a limit of
±10 V on the output of A1 would imply a limit of ±2.5 V on VCM
.
A nominal value of 100 kW for RN is suitable for most applica-
tions. A range of 200 W to 25 kW for RO will then provide a gain
range of 10 to 1,000. T he current through RO is VD/RO, so the
amplifiers must supply ±10 mV/200 W when the gain is at the
maximum value of 1,000 and VD is at ±10 mV.
T he circuit of Figure 4 is recommended for applications where
the common-mode input range is relatively low and differential
gain will be in the range of 10 to 1,000. This two op amp instrumen-
tation amplifier features independent adjustment of common-mode
rejection and differential gain. Input impedance is very high since
both inputs are applied to noninverting op amp inputs.
Rejecting common-mode inputs is most important in accurately
amplifying low-level differential signals. T wo factors determine
the CMR of this instrumentation amplifier configuration (assuming
infinite gain):
1. CMRR of the op amps
2. Matching of the resistor network (R3/R4 = R2/R1)

REV. A
OP220
In this instrumentation amplifier configuration, error due to
CMRR effect is directly proportional to the differential CMRR
of the op amps. For the OP220A/E, this combined CMRR is a
minimum of 98 dB. A combined CMRR value of 100 dB and
common-mode input range of ±2.5 V indicates a peak input-
referred error of only ±25 mV.
THREE OP AMP CONFIGURATION
A three op amp instrumentation amplifier configuration using
the OP220 and OP777 is recommended for applications requiring
high accuracy over a wide gain range. T his circuit provides
excellent CMR over a wide input range. As with the two op amp
instrumentation amplifier circuits, tight matching of the two op
amps provides a real boost in performance.
Resistor matching is the other factor affecting CMRR. Defining
Ad as the differential gain of the instrumentation amplifier and
assuming that R1, R2, R3 and R4 are approximately equal (RN
will be the nominal value), then CMRR will be approximately
AD divided by 4DR/RN. CMRR at differential gain of 100 would
be 88 dB with resistor matching of 0.1%. T rimming R1 to make
the ratio R3/R4 equal to R2/R1 will directly raise the CMRR
until it is limited by linearity and resistor stability considerations.

where AD is the instrumentation amplifier differential gain and
A02 is the open-loop gain of op amp A2. T his analysis assumes
equal values of R1, R2, R3, and R4. For example, consider an
OP220 with A02 of 700 V/mV. If the differential gain AD were
set to 700, the gain error would be 1/1.001 which is approxi-
mately 0.1%.
A simplifiechemic is shown in Figure 2. T he input stage

amplifying the common-mode voltage VCM. T he output stage

no sisr matching errors, the outputs of each amplifier will be:
Another effect of finite op amp gain is undesired feed
common-mode input. Defining A01 as the open-loop
amp A1, then the common-mode error (CME) at the
due to this effect will be approximately:

T he differential gain AD is 1 + 2R1/RO and the common-mode
input VCM is rejected.
T he OP220 offerbinatn of excellent dc perfor-
mance, wide inpsupply current drain that is
particularly attracentation amplifier design.
This three op amp instrumentation amplifier configuration using an
OP220 at the input and an OP777 at the output provides excellent
performance over a wide gain range with very low power consump-
tion. A gain range of 1 to 2,000 is practical and CMR of over
120 dB is readily achievable.
