OPA842

宽带低失真单位增益稳定的电压反馈运算放大器

The provides a level of speed and dynamic range previously unattainable in a monolithic op amp. Using unity-gain stable, voltage-feedback architecture with two internal gain stages, the OPA842 achieves exceptionally low harmonic distortion over a wide frequency range. The

.

*classic** differential input provides all the familiar benefits of precision op amps, such as bias current cancellation and very low inverting current noise compared with wideband current differential gain/phase performance, low-voltage noise, and high output current drive make the OPA842 ideal for most high dynamic range applications.

Unity-gain stability makes the OPA842 particularly suitable for low-gain differential amplifiers, transimpedance amplifiers, gain of +2 video line drivers, wideband integrators, and low-distortion analog-to-digital converter ADC buffers. Where higher gain or even lower harmonic distortion is required, consider the OPA843—a higher-gain bandwidth and lower-noise version of the OPA842.
