LTC6409 Datasheet PDF

●The LTC6409IUDB#TRMPBF is a very high speed low distortion Differential Amplifier for use with high-speed data-acquisition cards. Its input common mode range includes ground, so that a ground-referenced input signal can be DC-coupled, level-shifted and converted to drive an ADC differentially. The gain and feedback resistors are external, so that the exact gain and frequency response can be tailored to each application. For example, the amplifier could be externally compensated in a no-overshoot configuration, which is desired in certain time-domain applications. The LTC6409 is stable in a differential gain of 1. This allows for a low output noise in applications where gain is not desired. It draws 52mA of supply current and has a hardware shutdown feature which reduces current consumption to 100µA.
