Its input mon 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 pensated 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 52m A of supply current and has a hardware shutdown feature which reduces current consumption to 100µA. The LTC6409 is available in a pact 3mm × 2mm 10‑pin leadless QFN package and operates over a - 40°C to 125°C temperature range.
