The OPA4137UA is a quad FET-input Operational Amplifier designed for miniature applications. The input common-mode voltage range includes the positive supply-suitable for many single-supply applications. Quad version has identical specifications for maximum design flexibility. OPA137 op amp is easy to use, free from phase inversion and overload problems found in some FET-input amplifier. High performance, including linearity, is maintained as the amplifier swing to their specified limits. In addition, the combination of high slew rate (3.5V/ms) and wide bandwidth (1MHz) provide fast settling time assuring good dynamic response. Quad design feature completely independent circuitry for lowest crosstalk and freedom from interaction.
