Milpitas, Calif. Linear Technology has introduced a low noise, low distortion ADC driver. The low-power LTC6406 features a rail-to-rail input stage and an independently adjustable output common mode range.
Using a single 3-V supply, the LTC6406's differential outputs each swing from near ground to 2-V. This makes the amplifier suitable for level shifting signals to match the input range of 12-bit to 16-bit single supply differential input ADCs.
The LTC6406 offers a 3-GHz gain bandwidth and an unity gain bandwidth of 800 MHz.
The device achieves -90 dBc distortion performance for input frequencies from DC to 20MHz, and nearby -70 dBc distortion performance from DC to 50MHz. Current consumption is 18 mA, which can be reduced to 300 μA during periods of inactivity by use of a shutdown feature.
The LTC6406 is available in a 3 x 3mm 16-lead QFN package in both commercial (0°C to 70°C) and industrial (-40°C to 85°C) temperature ranges.
Pricing: Starts at $3.44 per unit in quantities of 1,000.
