Rail-to-Rail Input 3GHz Fully Differential ADC Driver

(PresseBox) (Ismaning, ) Linear Technology announces the LTC6406, a high-speed with low power ADC driver, low distortion and noise. It features a rail-to-rail input stage and an independently adjustable output common mode range. Using a single 3V supply, the LTC6406`s differential outputs each swing from near ground to 2V. As a result, this amplifier is ideal for level shifting signals to match the input range of 12-bit to 16-bit single supply differential input ADCs.

The LTC6406 is built for speed, performance and power efficiency. Its gain-bandwidth product is 3GHz, and its unity gain -3dB bandwidth is 800MHz. The LTC6406 achieves -90dBc distortion performance for input frequencies from DC to 20MHz, and nearby -70dBc distortion performance from DC to 50MHz. Noise is just 1.6nV/Hz. Operating on supplies from 2.7V to 3.5V, the LTC6406 is fully specified at 3V. This allows the amplifier to share the power supply used by many ADCs. Current consumption is just 18mA, which can be reduced to 300uA during periods of inactivity by use of a shutdown feature.

The LTC6406 achieves excellent dynamic performance with low power consumption,says Kris Lokere, Design Manager at Linear Technology.Its patentpending rail-to-rail input stage simplifies the task of translating a groundreferenced or supplyreferenced signal to the input range of popular high speed ADCs such as the LTC2206.

The LTC6406 is available in a 3mm x 3mm 16-lead QFN package in both commercial (0C to 70C) and industrial (-40C to 85C) temperature ranges.
