Analog Devices, Inc., which recently acquired Linear Technology Corporation, has announced the LTC6419, a dual 10GHz gain bandwidth product differential amplifier with very low input voltage noise ...

where gain is the amplifier’s fixed-voltage gain in decibels. Maxim ’s MAX9705 differential-audio amplifier, for example, is available in fixed-gain versions of 6, 12, 15.5, and 20 dB, and its input ...

This equation results in a 20-µV ripple on a differential-amplifier output. In the case of the single-ended input amplifier, the result would be 100 mV multiplied by the closed-loop gain.

Noise analysis for the single to differential FDA Once a set of resistor values are determined using these design equations, those can be placed into a noise analysis circuit to arrive at a total ...

Noise figures at maximum gain (26dB) and 100MHz input frequency are: 9.7dB noise figure, 44-dBm OIP3, and -100 dBc HD3. Gain control can be implemented via SPI bus or dedicated pins, with no external ...
