ELECTROSTATIC DISCHARGE SENSITIVITY 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.

7 APPLICATIONS INFORMATION The OPA3 series op amps are unity-gain stable and suitable for a wide range of general-purpose applications. Power-supply pins should be bypassed with nf ceramic capacitors or larger. The OPA3 series op amps are free from unexpected output phase-reversal common with FET op amps. Many FET-input op amps exhibit phase-reversal of the output when the input common-mode voltage range is exceeded. This can occur in voltage-follower circuits, causing serious problems in control-loop applications. All circuitry is completely independent in dual and quad versions, assuring normal behavior when one amplifier in a package is overdriven or shortcircuited. OFFSET VOLTAGE TRIM The OPA3 (single op amp version) provides offset voltage trim connections on pins and 5. Offset voltage can be adjusted by connecting a potentiometer as shown in Figure. This adjustment should be used only to null the offset of the op amp, not system offset or offset produced by the signal source. 2 3 V+ V 7 OPA3 (Single op amp only) OPA kω Trim Range: ±2mV typ FIGURE. OPA3 Offset Voltage Trim Circuit. INPUT BIAS CURRENT The input bias current is approximately 5pA at room temperature and increases with temperature as shown in the typical characteristic Input Bias Current vs Temperature. Input bias current also varies with common-mode voltage and power supply voltage. This variation is dependent on the voltage between the negative power supply and the common-mode input voltage. The effect is shown in the typical curve Input Bias Current vs Common-Mode Voltage. OPA3, 23, 43 7 SBOS4A
