LTC6404HUD-1#PBF

LTC6404HUD-1#PBF is a very low noise, low distortion, fully differential input/output amplifier optimized for 3V, single supply operation. The LTC6404-1 is unity-gain stable. The LTC6404 closed-loop bandwidth extends from DC to 600MHz. In addition to the normal unfiltered outputs (OUT+ and OUT–), the LTC6404 has a built-in 88.5MHz differential single-pole lowpass filter and an additional pair of filtered outputs (OUTF+, OUTF–). An input referred voltage noise of 1.5nV/√Hz makes the LTC6404 able to drive state-of-the-art 16-/18bit ADCs while operating on the same supply voltage, saving system cost and power. The LTC6404 is characterized and maintains its performance for supplies as low as 2.7V and can operate on supplies up to 5.25V. Applications include differential input A/D converter driver, single-ended to differential conversion/amplification, common mode level translation, low voltage, low noise, and signal processing.
