Low Power, Precision FET-INPUT OPERATIONAL AMPLIFIERS

DESCRIPTION

The OPA130 series of FET-input op amps combine precision dc performance with low quiescent current. Single, dual, and quad versions have identical specifi- cations 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.

This integrated circuit can be damaged by ESD. Burr-Brown 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 degrada- tion 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. ABSOLUTE MAXIMUM RATINGS NOTE: (1) Short-circuit to ground, one amplifier per package.
