LTC6403CUD-1#PBF

LTC6403CUD-1#PBF is a very low noise, low distortion, fully differential I/P/O/P amplifier optimized for 3V to 5V, single supply operation. This device's closed-loop bandwidth extends from DC to 200MHz. In addition to the normal unfiltered outputs (+OUT and –OUT), this device has a built-in 44.2MHz differential single-pole lowpass filter and an additional pair of filtered outputs (+OUTF, and –OUTF). An input referred voltage noise of 2.8nV/√Hz enables the device to drive state-of-the-art 14- to 18bit ADCs while operating on the same supply voltage, saving system cost and power. It maintains its performance for supplies as low as 2.7V. It draws only 10.8mA and has a hardware shutdown feature which reduces current consumption to 170µA. 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.
