● HIGH OUTPUT CURRENT: ±60mA  
● VERY LOW DIFF GAIN/PHASE ERROR:  
0.007%/0.008°  
feedback op amps. Fast settling time, excellent differ-  
ential gain/phase performance, low voltage noise and  
high output current drive make the OPA642 ideal for  
most high dynamic range applications.  
DESCRIPTION  
The OPA642 provides a level of speed and dynamic  
range previously unattainable in a monolithic op amp.  
Using a unity gain stable voltage feedback architec-  
ture with two internal gain stages, the OPA642 achieves  
exceptionally low harmonic distortion over a wide  
frequency 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  
Unity gain stability makes the OPA642 particularly  
suitable 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 OPA642
