Linear Technology has introduced the LTC6409 differential amplifier which is capable of driving DC to 100MHz signals with just 1.1nV/vHz noise and -88dBc HD2/HD3 distortion.

Built on SiGe BiCMOS process, the device features 10GHz gain-bandwidth product, 100dB SFDR up to 40MHz, and 1% settling time of 1.9ns.

Input common mode range is specified at 0V to 3.5V and output common mode range of 0.5V to 3.5V when using a single 5V supply.

Gain and feedback resistors are external, allowing the designer to configure the exact gain needed for each application. The amplifier is unity gain stable and high output current of up to 95mA allows it to drive lower value feedback and gain resistors, such as 150Ohm, resulting in very low output noise.

Current power consumption is 56mA max and a shutdown mode reduces this to 500uA when turned off. Turn-on time is typically 160ns.
