opa842器件手册

　　The OPA842 provides a level of speed and dynamic range

　　previously unattainable in a monolithic op amp. Using unitygain 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.
