THS3121

单路低噪声高输出驱动 475mA 电流反馈放大器

The THS3120 and are low-noise, high-voltage, high output current drive, current-feedback amplifiers designed to operate over a wide supply range of ±5 V to ±15 V for today"s high-performance applications.

The THS3120 offers a power saving mode by providing a power-down pin for reducing the 7-mA quiescent current of the device, when the device is not active.

These amplifiers provide well-regulated ac performance characteristics. Most notably, the 0.1-dB flat bandwidth is exceedingly high, reaching beyond 90 MHz. The unity-gain bandwidth of 130 MHz allows for good distortion characteristics at 10 MHz. Coupled with high 1700-V/µs slew rate, the THS3120 and THS3121 amplifiers allow for high output voltage swings at high frequencies.

The THS3120 and THS3121 are offered in an SOIC-8 D package and an MSOP-8 DGN PowerPAD package.
