The LTC6404-2 is an AC precision, very low noise, low distortion, fully differential input/output amplifier optimized for 3V, single supply operation. The LTC6404-2 is stable for gains exceeding 2V/V and has a closed-loop bandwidth extending from DC to 600MHz. A unity-gain stable LTC6404-1 is also available. In addition to the normal unfiltered outputs (OUT+ and OUT-), the LTC6404-2 has a built-in 88.5MHz differential single-pole lowpass ?lter and an additional pair of ?ltered outputs (OUTF+, and OUTF-). An input referred voltage noise of 1.5nV/√Hz makes the LTC6404-2 uniquely able to drive state-of-the-art 14- to 18-bit ADCs while operating on the same supply voltage, saving system cost and power. The LTC6404-2 is characterized, and maintains its performance for supplies as low as 2.7V. It draws only 29.8mA, and has a hardware shutdown feature which reduces current consumption to 250μA. The LTC6404-2 is available in a compact 3mm x 3mm 16-pin leadless QFN package and operates over a -40°C to 125°C temperature range.
