Total Harmonic Distortion 2 VPP Output, RL = 150 Ω, 0.6 AV = +2, f = 5 MHz (1) Typical Values represent the most likely parametric norm. (2) All limits are ensured by testing or statistical analysis. (3) Slew rate is the average of the rising and falling slew rates. (4) Unity gain operation for ±5 V and ±15 V supplies is with a feedback network of 510 Ω and 3 pF in parallel (see Application and Implementation). For +5V single supply operation, feedback is a direct short from the output to the inverting input. (5) AV = +2 operation with 2 kΩ resistors and 2 pF capacitor from summing node to ground.
