OPA842  
OPA842  
SBOS267A – NOVEMBER 2002 – REVISED DECEMBER 2002  
Wideband, Low Distortion, Unity-Gain Stable,  
Voltage-Feedback OPERATIONAL AMPLIFIER  
FEATURES  
DESCRIPTION  
The OPA842 provides a level of speed and dynamic range  
previously unattainable in a monolithic op amp. Using unity-  
gain stable, voltage-feedback architecture with two internal  
gain stages, the OPA842 achieves exceptionally low har-  
monic 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 BANDWIDTH: 400MHz  
GAIN-BANDWIDTH PRODUCT: 200MHz  
LOW INPUT VOLTAGE NOISE: 2.6nV/Hz  
VERY LOW DISTORTION: –93dBc (5MHz)  
HIGH OPEN-LOOP GAIN: 110dB  
FAST 12-BIT SETTLING: 22ns (0.01%)  
LOW DC VOLTAGE OFFSET: 300µV Typical  
PROFESSIONAL LEVEL DIFF GAIN/PHASE ERROR:  
0.003%/0.008°  
Unity-gain stability makes the OPA842 particularly suitable  
for low-gain differential amplifiers, transimpedance amplifi-  
ers, 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.
