LT6350CMS8#PBF

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 successive approximation register (SAR) ADCs. The two op amp topology features very low noise op amps, that can support SNR <gt/>110dB in a 1MHz bandwidth. The input op amp is trimmed for constant low input-referred voltage offset over the input range to prevent VOS steps from degrading distortion. On a single 5V supply, the outputs can swing from 55mV to 4.945V. With the addition of a negative supply, this can swing from 0V to 4.945V. Output common mode voltage is set by applying a voltage to the +IN2 pin. Typical applications are 16-bit and 18-bit SAR ADC drivers, single-ended to differential conversion, differential line driver.
