LT6350CMS8#TRPBF

LT6350 is a 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, it can swing from 0V to 4.945V. Output common mode voltage is set by applying a voltage to the +IN2 pin. Application includes 16-bit and 18-bit SAR ADC drivers, single-ended to differential conversion, differential line driver.
