DESCRIPTION
The LT®6350 is a rail-to-rail input and output low noise single-ended to differential converter/ADC driver featuring fast settling time. It converts a high or low impedance, single-ended input signal to a low impedance, balanced, differential output suitable for driving high performance differential succesive approximation register (SAR) ADCs. The two op amp topology features very low noise op amps, that can support SNR >110dB in a 1MHz bandwidth.
