high-performance applications.
High Output Current Drive: 475 mA
The THS3120 offers a power saving mode by
High Slew Rate:
providing a power-down pin for reducing the 7-mA
quiescent current of the device, when the device is

performance characteristics. Most notably, the 0.1-dB
Power-Down Feature: (THS3120 Only)
flat bandwidth is exceedingly high, reaching beyond
90 MHz. The unity-gain bandwidth of 130 MHz allows
