LTC6403-1 200MHz, Low Noise, Low Power Fully Differential Input/Output Amplifier/Driver FEATURES DESCRIPTION n Very Low Distortion: (2V , 3MHz): 95dBc The LTC 6403-1 is a precision, very low noise, low dis- P-P n Fully Differential Input and Output tortion, fully differential input/output amplifier optimized n Low Noise: 2.8nV/Hz Input-Referred for 3V to 5V, single supply operation. The LTC6403-1 is n 200MHz Gain-Bandwidth Product unity gain stable. The LTC6403-1 closed-loop bandwidth n Built-In Clamp: Fast Overdrive Recovery extends from DC to 200MHz. In addition to the normal n Slew Rate: 200V/s unfiltered outputs (+OUT and OUT), the LTC6403-1 has a n Adjustable Output Common Mode Voltage built-in 44.2MHz differential single-pole lowpass filter and n Rail-to-Rail Output Swing an additional pair of filtered outputs (+OUTF, and OUTF). n Input Range Extends to Ground An input referred voltage noise of 2.8nV/Hz enables the n Large Output Current: 60mA (Typ) LTC6403-1 to drive state-of-the-art 14- to 18-bit ADCs n DC Voltage Offset <1.5mV (Max) while operating on the same supply voltage, saving system n 10.8mA Supply Current cost and power. The LTC6403-1 maintains its performance n 2.7V to 5.25V Supply Voltage Range for supplies as low as 2.7V. It draws only 10.8mA, and n Low Power Shutdown has a hardware shutdown feature which reduces current n Tiny 3mm 3mm 0.75mm 16-Pin QFN Package consumption to 170A. The LTC6403-1 is available in a compact 3mm 3mm APPLICATIONS 16-pin leadless QFN package and operates over a 40C to 125C temperature range. n Differential Input A/D Converter Driver L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of Analog n Single-Ended to Differential Conversion/Amplification Devices, Inc.
