DESCRIPTION The INA117 is a precision unity-gain difference amplifier with very high common-mode input voltage range. It is a single monolithic IC consisting of a precision op amp and integrated thin-film resistor network. It can accurately measure small differential voltages in the presence of common-mode signals up to ±200V. The INA117 inputs are protected from momentary common-mode or differential overloads up to ±500V. In many applications, where galvanic isolation is not essential, the INA117 can replace isolation amplifiers. This can eliminate costly isolated input-side power supplies and their associated ripple, noise and quiescent current. The INA117’s 0.001% nonlinearity and 200kHz bandwidth are superior to those of conventional isolation amplifiers.

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.

COMMON-MODE REJECTION Common-mode rejection (CMR) of the INA117 is dependent on the input resistor network, which is laser-trimmed for accurate ratio matching. To maintain high CMR, it is important to have low source impedances driving the two inputs. A 75Ω resistance in series with pin 2 or 3 will decrease CMR from 86dB to 72dB.

Resistance in series with the reference pins will also degrade CMR. A 4Ω resistance in series with pin 1 or 5 will decrease CMRR from 86dB to 72dB. Most applications do not require trimming. Figures 2 and 3 show optional circuits that may be used for trimming offset voltage and common-mode rejection. TRANSFER FUNCTION Most applications use the INA117 as a simple unity-gain difference amplifier. The transfer function is: VO = V3 – V2
100Ω
Offset adjustment is regulated— insensitive to power supply variations.

V3 and V2 are the voltages at pins 3 and 2.

MEASURING CURRENT The INA117 can be used to measure a current by sensing the voltage drop across a series resistor, RS. Figure 4 shows the INA117 used to measure the supply currents of a device under test. The circuit in Figure 5 measures the output current of a power supply. If the power supply has a sense connection, it can be connected to the output side of RS to eliminate the voltage-drop error. Another common application is current-to-voltage conversion, as shown in Figure 6.

INA117 SBOS154A
Example: For a 1V/mA transfer function, the nominal, uncorrected value for RS would be 1kΩ. A slightly larger value, RS' = 1002.6Ω, compensates for the gain error due to loading.
In all cases, the sense resistor imbalances the input resistor matching of the INA117, degrading its CMR. Also, the input impedance of the INA117 loads RS, causing gain error in the voltage-to-current conversion. Both of these errors can be easily corrected.
The 380kΩ term in the equation for RS' has a tolerance of ±25%, so sense resistors above approximately 400Ω may require trimming to achieve gain accuracy better than 0.02%.
The CMR error can be corrected with the addition of a compensation resistor, RC, equal in value to RS as shown in Figures 4, 5, and 6. If RS is less than 20Ω, the degradation in CMR is negligible and RC can be omitted. If RS is larger than approximately 2kΩ, trimming RC may be required to achieve greater than 86dB CMR. This is because the actual INA117 input impedances have 1% typical mismatch.
Of course, if a buffer amplifier is added as shown in Figure 7, both inputs see a low source impedance, and the sense resistor is not loaded. As a result, there is no gain error or CMR degradation. The buffer amplifier can operate as a unity gain buffer or as an amplifier with non-inverting gain. Gain added ahead of the INA117 improves both CMR and signal-to-noise. Added gain also allows a lower voltage drop across the sense resistor. The OPA1013 is a good choice for the buffer amplifier since both its input and output can swing close to its negative power supply.
If RS is more than approximately 100Ω, the gain error will be greater than the 0.02% specification of the INA117. This gain error can be corrected by slightly increasing the value of RS. The corrected value, RS', can be calculated by: R S' =

Figure 8 shows very high input impedance buffer used to measure low leakage currents. Here, the buffer op amp is powered with an isolated, split-voltage power supply. Using an isolated power supply allows full ±200V common-mode input range.
these resistors produces approximately 550nV/√Hz noise. The internal op amp contributes virtually no excess noise at frequencies above 100Hz. Many applications may be satisfied with less than the full 200kHz bandwidth of the INA117. In these cases, the noise can be reduced with a low-pass filter on the output. The twopole filter shown in Figure 9 limits bandwidth to 1kHz and reduces noise by more than 15:1. Since the INA117 has a 1/f noise corner frequency of approximately 100Hz, a cutoff frequency below 100Hz will not further reduce noise.

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check 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) (3)
MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
