SBOS267A NOVEMBER 2002 REVISED DECEMBER 2002
Wideband, Low Distortion, Unity-Gain Stable, Voltage-Feedback OPERATIONAL AMPLIFIER
FEATURES
q UNITY-GAIN BANDWIDTH: 400MHz q GAIN-BANDWIDTH PRODUCT: 200MHz q LOW INPUT VOLTAGE NOISE: 2.6nV/Hz q VERY LOW DISTORTION: 93dBc (5MHz) q HIGH OPEN-LOOP GAIN: 110dB q FAST 12-BIT SETTLING: 22ns (0.01%) q LOW DC VOLTAGE OFFSET: 300µV Typical q PROFESSIONAL LEVEL DIFF GAIN/PHASE ERROR: 0.003%/0.008°
DESCRIPTION
The OPA842 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 OPA842 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 OPA842 ideal for most high dynamic range applications. Unity-gain stability makes the OPA842 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 OPA842.

Exposure to absolute maximum conditions for extended periods may degrade device reliability. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those specified is not implied.
ELECTROSTATIC DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
