LTC6360
Very Low Noise Single-Ended
SAR ADC Driver
with True Zero Output
Description Features The LTC®6360 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 16-bit levels (AV = 1). Output Swings to True Zero on Single Supply

n 3mm × 3mm 8-Pin DFN and 8-lead MSOP Packages n n n n n 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 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. 16-Bit and 18-Bit SAR ADC Driver High Speed Buffer Amplifiers …
