The THS3470 is a high-speed current-feedback amplifier (CFA) with a high linear-output current drive (1A), high slew rate (4000V/µs), and wide supply range (60V). The device is stable over a wide range of capacitive loads and supports up to 2A of peak output current that these applications require. The THS3470 has a bandwidth of 100MHz with low-noise and distortion providing great large-signal performance for heavy resistive loads as well.

In addition to high speed and power performance, the THS3470 features a number of useful features such as temperature monitoring, output current monitoring, output current limiting, and output current protection. The output current features of the device can be manually enabled or driven by various flag outputs from the device providing even greater modularity in the use case of the device.

The THS3470 is available in a VQFN-42 (REB) package, providing small-size with an exposed top-side thermal pad for direct heat transfer to a heat sink. The THS3470 is characterized for operation over the wide temperature range of –40°C to +85°C.
