are

high-voltage,

low-distortion,

high-speed,

current-feedback

amplifiers designed to operate over a wide supply

range of

±5 V to ±15 V for applications requiring

Low Noise

large, linear output signals such as Pin, Power FET,

and VDSL line drivers.

– 17 pA/

The THS3095 features a power-down pin (PD) that

puts the amplifier in low power standby mode, and

– 2 nV/
