The THS3120 EVM User's Guide is included within the Datasheet.
The THS3120 EVM is a turnkey module that allows you to evaluate the low-noise, high-voltage, high output current drive, current-feedback amplifier designed to operate over a wide supply range for high performance applications. The THS3120 EVM offers a power saving mode by providing a power-down pin, reducing the quiescent current when the device is not active.
