OPA 843
SBOS268A DECEMBER 2002 OCTOBER 2003
Wideband, Low Distortion, Medium Gain, Voltage-Feedback OPERATIONAL AMPLIFIER
FEATURES
q HIGH BANDWIDTH: 260MHz (G = +5) q GAIN BANDWIDTH PRODUCT: 800MHz q LOW INPUT VOLTAGE NOISE: 2.0nV/Hz q VERY LOW DISTORTION: 96dBc (5MHz) q HIGH OPEN-LOOP GAIN: 110dB q FAST 12-BIT SETTLING: 10.5ns (0.01%) q LOW INPUT OFFSET VOLTAGE: 300µV q OUTPUT CURRENT: ±100mA
DESCRIPTION
The OPA843 provides a level of speed and dynamic range previously unattainable in a monolithic op amp. Using a high Gain Bandwidth (GBW), two gain-stage design, the OPA843 gives a medium gain range device with exceptional dynamic range. The "classic" differential input complements this high dynamic range with DC precision beyond most high-speed amplifier products. Very low input offset voltage and current, high Common-Mode Rejection Ratio (CMRR) and PowerSupply Rejection Ratio (PSRR), and high open-loop gain combine to give a high DC precision amplifier along with low noise and high 3rd-order intercept. 12- to 16-bit converter interfaces will benefit from this combination of features. High-speed transimpedance applications can be implemented with exceptional DC precision as well. Differential configurations using two OPA843s can deliver very low distortion to high output voltages, as shown below.

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.
