3mm × 3mm × 0.75mm QFN Packages The LTC®6405 is a very low noise, low distortion, fully
differential input/output amplifier optimized for 5V, single
supply operation. The LTC6405 input common mode range
is rail-to-rail, while the output common 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 common mode range for driving 12-bit
to 16-bit single supply, differential input ADCs. n A 2.7GHz gain-bandwidth product results in 65dB linearity …
