ELECTROSTATICDISCHARGE SENSITIVITY

This integrated circuit can be damaged by ESD. Burr-Brownrecommends that all integrated circuits be handled withappropriate precautions. Failure to observe proper handlingand installation procedures can cause damage.

ESD damage can range from subtle performance degradationto complete device failure. Precision integrated circuits maybe more susceptible to damage because very small parametricchanges could cause the device not to meet its publishedspecifications.

APPLICATION INFORMATIONFigure 1 shows the basic connections required for operationof the INA105. Power supply bypass capacitors should beconnected close to the device pins.

The differential input signal is connected to pins 2 and 3 asshown. The source impedances connected to the inputs mustbe nearly equal to assure good common-mode rejection. A5Ω mismatch in source impedance will degrade the com-mon-mode rejection of a typical device to approximately80dB. If the source has a known mismatch in source imped-ance, an additional resistor in series with one input can beused to preserve good common-mode rejection.

The output is referred to the output reference terminal (pin1) which is normally grounded. A voltage applied to the Refterminal will be summed with the output signal. This can beused to null offset voltage as shown in Figure 2. The sourceimpedance of a signal applied to the Ref terminal should beless than 10Ω to maintain good common-mode rejection.

Do not interchange pins 1 and 3 or pins 2 and 5, even thoughnominal resistor values are equal. These resistors are lasertrimmed for precise resistor ratios to achieve accurate gainand highest CMR. Interchanging these pins would not pro-vide specified performance.

FIGURE 2. Offset Adjustment.

FIGURE 3. Precision Difference Amplifier.

For low source impedance applications, an input stage using OPA27 opamps will give the best low noise, offset, and temperature drift performance.At source impedances above about 10kΩ, the bias current noise of theOPA27 reacting with the input impedance begins to dominate the noiseperformance. For these applications, using the OPA111 or dual OPA2111FET input op amp will provide lower noise performance. For lower cost usethe OPA121 plastic. To construct an electrometer use the OPA128.
