说明

The THS4211 and THS4215 are high slew rate, unity-gain stable, voltage feedback amplifiers designed to run from supply voltages as low as 5 V and as high as 15 V. The THS4215 offers the same performance as the THS4211 with the addition of power-down capability. The combination of high slew rate, wide bandwidth, low distortion, and unity-gain stability make the THS4211 and THS4215 high-performance devices across multiple ac specifications.

Designers using the THS4211 are rewarded with higher dynamic range over a wider frequency band without the stability concerns of decompensated amplifiers. These devices are available in SOIC, MSOP with PowerPAD, and leadless MSOP with PowerPAD packages.
