LTC6360CMS8E#PBF

LTC6360CMS8E#PBF is a very low noise, high precision, high-speed amplifier suitable for driving SAR ADCs. The LTC6360 features a total output noise of 2.3nV/√Hz combined with 150ns settling time to 16bit levels (AV = 1). While powered from a single 5V supply, the amplifier output can swing to 0V while maintaining high linearity. This is made possible with the inclusion of a very low noise on-chip charge pump that generates a negative voltage to bias the output stage of the amplifier, increasing the allowable negative voltage swing. Applications include 16bit and 18bit SAR ADC drivers, high-speed buffer amplifiers, and low noise signal processing.
