Description
AI
The LTC6360 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/√Hzcombined with 150ns settling time to 16-bit 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.The LTC6360 is available in a compact 3mm × 3mm, 8-pin leadless DFN package and an 8-pin MSOP package with exposed pad and operates over a –40°C to 125°C temperature range.Applications16-Bit and 18-Bit SAR ADC DriverHigh Speed Buffer AmplifiersLow Noise Signal Processing
