  • OPA140  - The device has the SAME FUNCTIONALITY as the compared device, but is not pin-for-pin equivalent and may not be parametrically equivalent.   Modern JFET-input op amp with wider bandwidth (11MHz), lower noise (5.1nV/√Hz), lower power consumption (1.8mA) & higher DC precision (120µV max offset voltage)

Description

The OPAx132 series of FET-input operational amplifiers provides highspeed and excellent DC performance. The combination of high slew rate and wide bandwidth provide fast settling time. Single, dual, and quad versions have identical specifications for maximum design flexibility. High performance grades are available in the single and dual versions. All are ideal for general-purpose, audio, data acquisition and communications applications, especially where high source impedance is encountered.

The OPAx132 operational amplifiers are easy to use and free from phase inversion and overload problems often found in common FET-input operational amplifiers. Input cascode circuitry provides excellent common-mode rejection and maintains low input bias current over its wide input voltage range. The OPAx132 series of operational amplifiers are stable in unity gain and provide excellent dynamic behavior over a wide range of load conditions, including high load capacitance. Dual and quad versions 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
