OPA642N/250 DESCRIPTION

The OPA642 provides a level of speed and dynamicrange previously unattainable in a monolithic op amp.Using a unity gain stable voltage feedback architec-ture with two internal gain stages, the OPA642 achievesexceptionally low harmonic distortion over a widefrequency range. The “classic” differential input pro-vides all the familiar benefits of precision op amps,such as bias current cancellation and very low invert-ing current noise compared with wideband current

OPA642N/250 APPLICATIONS

l ADC/DAC BUFFER AMPLIFIERl LOW DISTORTION IF AMPLIFIERl HIGH RESOLUTION IMAGINGl MEDICAL IMAGINGl LOW NOISE PREAMPLIFIERl HIGH CMR DIFFERENCING AMPLIFIERl TEST INSTRUMENTATIONl PROFESSIONAL AUDIOfeedback op amps. Fast settling time, excellent differ-ential gain/phase performance, low voltage noise andhigh output current drive make the OPA642 ideal formost high dynamic range applications.Unity gain stability makes the OPA642 particularlysuitable for low gain differential amplifiers,transimpedance amplifiers, gain of +2 video line driv-ers, wideband integrators and low distortion ADC buff-ers. Where higher gain or even lower harmonic distor-tion is required, consider the OPA643—a higher gain-bandwidth and lower noise version of the OPA642Measured80dB SFDRHigh Dynamic Range 10MSPS Digitizer1OPA642SBOS024
