OPA842IDG4 Datasheet

Linear - Amplifiers - Instrumentation, OP Amps, Buffer Amps


The OPA842IDG4 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 OPA842IDG4 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 OPA842IDG4 ideal for most high dynamic range applications.Unity-gain stability makes the OPA842IDG4 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 OPA842IDG4.
