Operational Amplifiers - Op Amps High-Speed Precision Difet
The OPA643 provides a level of speed and dynamic range previously unattainable in a monolithic op amp. Using a de-compensated voltage feedback architecture with two internal gain stages, the OPA643 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 feedback op amps. High slew rate and open-loop gain, along with low input noise and high output current drive make the OPA643 ideal for very high dynamic range requirements.
The high gain bandwidth product for the gain 3 stable OPA643 makes it particularly suitable for wideband transimpedance amplifiers and moderate gain IF amplifier applications. External compensation techniques may be used to apply the OPA643 at low gains giving exceptionally low distortion and frequency response flatness. Where unity gain stability with comparable distortion performance is required, consider the OPA642.
