Description
LTC6362
Driving 18-Bit SAR ADC
The LTC
®
6362 is a low power, low noise differential op
amp with rail-to-rail input and output swing that has been
optimized to drive low power SAR ADCs. The amplifier
may be configured to buffer a fully differential input signal
or convert a single-ended input signal to a differential
output signal.
The LTC2380/LTC2379/LTC2378/LTC2377/LTC2376 are low
power, low noise ADCs with serial outputs that can operate
from a single 2.5V supply. The DC1805A demonstrates
the DC and AC performance of the LTC6362 driving the
LTC2379-18 when used in conjunction with the DC590B
QuikEval™ and DC718 fast DACs data collection boards.
Use the DC590B to demonstrate DC performance such
as peak-to-peak noise and DC linearity. Use the DC718
if precise sampling rates are required or to demonstrate
AC performance such as SNR, THD, SINAD and SFDR.
The DC1805A is intended to demonstrate recommended
grounding, component placement and selection, routing
and bypassing for LTC6362 and the ADC.
