Single, dual, and quad versions have identical specifications for maximum design flexibility. They are ideal for general-purpose, portable, and battery operated applications, especially with high source impedance. OPA130 op amps are easy to use and free from phase inversion and overload problems often found in common FET-input op amps. Input cascode circuitry provides excellent common-mode rejection and maintains low input bias current over its wide input voltage range. OPA130 series op amps are stable in unity gain and provide excellent dynamic behavior over a wide range of load conditions, including high load capacitance. Dual and quad designs feature completely independent circuitry for lowest crosstalk and freedom from interaction, even when overdriven or overloaded. Single and dual versions are available in 8-pin DIP and SO-8 surface-mount packages. Quad is available in 14-pin DIP and SO-14 surface-mount packages. All are specified for –40°C to +85°C operation.

Power supply pins should be bypassed with 10nF ceramic capacitors or larger. 10nF 100kΩ 7 1 2 OPA130 op amps are free from unexpected output phasereversal 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. OPA130 series op amps are free from this undesirable behavior. All circuitry is completely independent in dual and quad versions, assuring normal behavior when one amplifier in a package is overdriven or short-circuited. 5 3 10nF OPA130 4 6 OPA130 single op amp only. Use offset adjust pins only to null offset voltage of op amp—see text. V– FIGURE 1. OPA130 Offset Voltage Trim Circuit. INPUT BIAS CURRENT OPERATING VOLTAGE The input bias current is approximately 5pA at room temperature and increases with temperature as shown in the typical performance curve “Input Bias Current vs Temperature.” Input stage cascode circuitry assures that the input bias current remains virtually unchanged throughout the full input common-mode range of the OPA130. See the typical performance curve “Input Bias Current vs Common-Mode Voltage.” OPA130 series op amps operate with power supplies from ±2.25V to ±18V with excellent performance. Although specifications are production tested with ±15V supplies, most behavior remains unchanged throughout the full operating voltage range. Parameters which vary significantly with operating voltage are shown in the typical performance curves. OFFSET VOLTAGE TRIM Offset voltage of OPA130 series amplifiers is laser trimmed and usually requires no user adjustment. The OPA130 (single op amp version) provides offset voltage trim connections on pins 1 and 5. Offset voltage can be adjusted by connecting a potentiometer as shown in Figure 1. This adjustment should be used only to null the offset of the op amp, not to adjust system offset or offset produced by the signal source. Nulling offset that is not produced by the amplifier will change the offset voltage drift behavior of the op amp. ® 7 OPA130, 2130, 4130
