DESCRIPTION
LTC2393-16/LTC2392-16/
LTC2391-16, 1MSPS, 0.5MSPS,
0.25MSPS Low Noise ADC
The LTC2393-16 family are low noise high speed ADCs
with both parallel and serial outputs that can operate from
a single 5V supply. The LTC2393-16 family supports a
large ±4.096V fully differential input range. This makes
them ideal for high performance applications that require
maximum dynamic range. Demonstration circuit 1501A
provides the user a means of evaluating the performance
of these ADCs in both parallel and serial modes and is

intended to dem onstrate recommended grounding, part
placement, routing and bypassing for this family of parts.
Also several suggested driver circuits for the analog inputs
will be presented.
