DESCRIPTION  
The INA333 is a low-power, precision instrumentation amplifier offering excellent accuracy. The versatile 3-op  
amp design, small size, and low power make it ideal for a wide range of portable applications.  
A single external resistor sets any gain from 1 to 1000. The INA333 is designed to use an industry-standard gain  
equation: G = 1 + (100kΩ/RG).  
The INA333 provides very low offset voltage (25 mV at 25°C, G ≥ 100), excellent offset voltage drift (0.2 mV/°C,  
G ≥ 100), and high common-mode rejection (100 dB at 25°C, G ≥ 10). It operates with power supplies as low as  
1.8 V (±0.9V), and quiescent current is only 50 mA—ideal for battery-operated systems. Using autocalibration  
techniques to ensure excellent precision over the extended industrial temperature range, the INA333 also offers  
exceptionally low noise density (55 nV/√Hz) that extends down to dc.  
The INA333 is is specified over the TA = –55°C to +210°C temperature range.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with  
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.  
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more  
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

(1) Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions for extended periods may  
degrade device reliability. These are stress ratings only, and functional operation of the device at these or any other conditions beyond  
those specified is not implied.  
(2) Input terminals are diode-clamped to the power-supply rails. Input signals that can swing more than 0.3V beyond the supply rails should  
be current limited to 10mA or less.  
(3) Short-circuit to ground.

APPLICATION INFORMATION  
Application information below is provided for  
commercial temperature as a reference and not for  
high temperature.  
SETTING THE GAIN  
Gain of the INA333 is set by a single external  
resistor, RG, connected between pins 1 and 8. The  
value of RG is selected according to Equation 1:  
It is not recommonded to use gain < 100 for the high  
temperature (210°C) application. A filter is needed  
between Pin 1 and Pin 9 for gain = 100 and  
gain = 1000 in 210°C application. Recommended  
resistor value is 3.5 kΩ and capacitor value is 10 nF.  
G = 1 + (100 kΩ/RG)  
(1)  
(1)  
Table 2 lists several commonly-used gains and  
resistor values. The 100 kΩ term in Equation 1  
comes from the sum of the two internal feedback  
resistors of A1 and A2. These on-chip resistors are  
laser trimmed to accurate absolute values. The  
accuracy and temperature coefficient of these  
resistors are included in the gain accuracy and drift  
specifications of the INA333.  
Figure 34 shows the basic connections required for  
operation of the INA333. Good layout practice  
mandates the use of bypass capacitors placed close  
to the device pins as shown.  
The output of the INA333 is referred to the output  
reference (REF) terminal, which is normally  
grounded. This connection must be low-impedance to  
assure good common-mode rejection. Although 15 Ω  
or less of stray resistance can be tolerated while  
maintaining specified CMRR, small stray resistances  
of tens of ohms in series with the REF pin can cause  
noticeable degradation in CMRR.  
The stability and temperature drift of the external gain  
setting resistor, RG, also affects gain. The contribution  
of RG to gain accuracy and drift can be directly  
inferred from the gain Equation 1. Low resistor values  
required for high gain can make wiring resistance  
important. Sockets add to the wiring resistance and  
contribute additional gain error (possibly an unstable  
gain error) in gains of approximately 100 or greater.  
To ensure stability, avoid parasitic capacitance of  
more than a few picofarads at the RG connections.  
Careful matching of any parasitics on both RG pins  
maintains optimal CMRR over frequency.

INTERNAL OFFSET CORRECTION  
Without a bias current path, the inputs will float to a  
potential that exceeds the common-mode range of  
the INA333, and the input amplifiers will saturate. If  
the differential source resistance is low, the bias  
current return path can be connected to one input  
(see the thermocouple example in Figure 36). With  
higher source impedance, using two equal resistors  
provides a balanced input with possible advantages  
of lower input offset voltage as a result of bias current  
and better high-frequency common-mode rejection.  
The INA333 internal op amps use an auto-calibration  
technique with a time-continuous 350-kHz op amp in  
the signal path. The amplifier is zero-corrected every  
8 ms using a proprietary technique. Upon power-up,  
the amplifier requires approximately 100 ms to  
achieve specified VOS accuracy. This design has no  
aliasing or flicker noise.  
OFFSET TRIMMING  
Most applications require no external offset  
adjustment; however, if necessary, adjustments can  
be made by applying a voltage to the REF terminal.  
Figure 35 shows an optional circuit for trimming the  
output offset voltage. The voltage applied to REF  
terminal is summed at the output. The op amp buffer  
provides low impedance at the REF terminal to  
preserve good common-mode rejection.

NOISE PERFORMANCE  
INPUT COMMON-MODE RANGE  
The auto-calibration technique used by the INA333  
results in reduced low frequency noise, typically only  
50 nV/√Hz, (G = 100). The spectral noise density can  
be seen in detail in Figure 10. Low frequency noise of  
the INA333 is approximately 1 mVPP measured from  
0.1 Hz to 10 Hz, (G = 100).  
The linear input voltage range of the input circuitry of  
the INA333 is from approximately 0.1 V below the  
positive supply voltage to 0.1 V above the negative  
supply. As a differential input voltage causes the  
output voltage to increase, however, the linear input  
range is limited by the output voltage swing of  
amplifiers A1 and A2. Thus, the linear common-mode  
input range is related to the output voltage of the  
complete amplifier. This behavior also depends on  
supply voltage—see Typical Characteristic curves  
Typical Common-Mode Range vs Output Voltage  
(Figure 22 to Figure 25).  
INPUT BIAS CURRENT RETURN PATH  
The input impedance of the INA333 is extremely  
high—approximately 100 GΩ. However, a path must  
be provided for the input bias current of both inputs.  
This input bias current is typically ±70 pA. High input  
impedance means that this input bias current  
changes very little with varying input voltage.  
Input overload conditions can produce an output  
voltage that appears normal. For example, if an input  
Input circuitry must provide a path for this input bias  
current for proper operation. Figure 36 illustrates  
various provisions for an input bias current path.

overload condition drives both input amplifiers to the  
respective positive output swing limit, the difference  
voltage measured by the output amplifier is near  
zero. The output of the INA333 is near 0 V even  
though both inputs are overloaded.

(1) R1 creates proper common-mode voltage, only for low-voltage  
operation—see the Single-Supply Operation section.  
Figure 37. Single-Supply Bridge Amplifier  
LOW VOLTAGE OPERATION  
The INA333 can be operated on power supplies as  
low as ±0.9 V. Most parameters vary only slightly  
throughout this supply voltage range—see the Typical  
Characteristics section. Operation at very low supply  
voltage requires careful attention to assure that the  
input voltages remain within the linear range. Voltage  
swing requirements of internal nodes limit the input  
common-mode range with low power-supply voltage.  
INPUT PROTECTION  
The input terminals of the INA333 are protected with  
internal diodes connected to the power-supply rails.  
These diodes clamp the applied signal to prevent it  
from damaging the input circuitry. If the input signal  
voltage can exceed the power supplies by more than  
0.3 V, the input signal current should be limited to  
less than 10 mA to protect the internal clamp diodes.  
This current limiting can generally be done with a  
series input resistor. Some signal sources are  
inherently current-limited and do not require limiting  
resistors.

Characteristic  
curves

Common-Mode Range vs Output Voltage (Figure 22  
to Figure 25) show the range of linear operation for  
various supply voltages and gains.  
SINGLE-SUPPLY OPERATION  
GENERAL LAYOUT GUIDELINES  
The INA333 can be used on single power supplies of  
+1.8 V to +5.5 V. Figure 37 illustrates a basic  
single-supply circuit. The output REF terminal is  
connected to mid-supply. Zero differential input  
voltage demands an output voltage of mid-supply.  
Actual output voltage swing is limited to  
approximately 50 mV above ground, when the load is  
referred to ground as shown. The typical  
characteristic curve Output Voltage Swing vs Output  
Current (Figure 31) shows how the output voltage  
swing varies with output current.  
Attention to good layout practices is always  
recommended. Keep traces short and, when  
possible, use a printed circuit board (PCB) ground  
plane with surface-mount components placed as  
close to the device pins as possible. Place a 0.1-mF  
bypass capacitor closely across the supply pins.  
These guidelines should be applied throughout the  
analog circuit to improve performance and provide  
benefits  
such  
as  
reducing  
the  
electromagnetic-interference (EMI) susceptibility.  
With single-supply operation, VIN+ and VIN– must both  
be 0.1V above ground for linear operation. For  
instance, the inverting input cannot be connected to  
ground to measure a voltage connected to the  
noninverting input.  
Instrumentation amplifiers vary in the susceptibility to  
radio-frequency interference (RFI). RFI can generally  
be identified as a variation in offset voltage or dc  
signal levels with changes in the interfering RF signal.  
The INA333 has been specifically designed to  
minimize susceptibility to RFI by incorporating  
passive RC filters with an 8-MHz corner frequency at  
the VIN+ and VIN– inputs. As a result, the INA333  
demonstrates remarkably low sensitivity compared to  
previous generation devices. Strong RF fields may  
continue to cause varying offset levels, however, and  
may require additional shielding.  
To illustrate the issues affecting low voltage  
operation, consider the circuit in Figure 37. It shows  
the INA333 operating from a single 3-V supply. A  
resistor in series with the low side of the bridge  
assures that the bridge output voltage is within the  
common-mode range of the amplifier inputs.

Additional application ideas are shown in Figure 38 to  
Figure 41.

http://www.ti.com/productcontent for the latest availability information and additional product content details.  
TBD: The Pb-Free/Green conversion plan has not been defined.  
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements  
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered  
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.  
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and  
package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS  
compatible) as defined above.  
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame  
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
