LTC6403-1

www.DataSheet4U.com LTC6403-1 200MHz, Low Noise, Low Power Fully Differential Input/Output Amplifier/Driver DESCRIPTION The LTC®6403-1 is a precision, very low noise, low distortion, fully differential input/output amplifier optimized for 3V to 5V, single supply operation. The LTC6403-1 is unity gain stable. The LTC6403-1 closed-loop bandwidth extends from DC to 200MHz. In addition to the normal unfiltered outputs (+OUT and –OUT), the LTC6403-1 has a built-in 44.2MHz differential single-pole low pass filter and an additional pair of filtered outputs (+OUTF, and –OUTF). An input referred voltage noise of 2.8nV/√⎯H⎯z enables the LTC6403-1 to drive state-of-the-art 14- to 18-bit ADCs while operating on the same supply voltage, saving system cost and power. The LTC6403-1 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. The LTC6403-1 is available in a compact 3mm × 3mm 16-pin leadless QFN package and operates over a –40°C to 85°C temperature range. , LT, LTC and LTM are registered trademarks of Linear Technology Corporation.
