LTC6405 Datasheet | Linear Technology

.. LTC6405 2.7GHz, 5V, Low Noise, Rail-to-Rail Input Differential Amplifier/Driver DESCRIPTION The LTC®6405 is a very low noise, low distortion, fully differential input/output amplifier optimized for 5V, single supply operation. The LTC6405 input mon mode range is rail-to-rail, while the output mon mode voltage is independently adjustable by applying a voltage on the VOCM pin. This makes the LTC6405 ideal for level shifting signals with a wide mon mode range for driving 12-bit to 16-bit single supply, differential input ADCs. A 2.7GHz gain-bandwidth product results in 65d B linearity for 50MHz input signals. The LTC6405 is unity gain stable and the closed-loop bandwidth extends from DC to 800MHz. The output voltage swing extends from near-ground to 4V, to be patible with a wide range of ADC converter input requirements. The LTC6405 draws only 18m A, and has a hardware shutdown feature which reduces current consumption to 400μA. The LTC6405 is available in a pact 3mm × 3mm 16-pin leadless QFN package, as well as an 8-lead MSOP package, and operates over a - 40°C to 85°C temperature range.
