Linear Technology DC1783A-A Demo Manual

LTC2377/LTC2376: 18-Bit/16-Bit, 2Msps/1.6Msps/1Msps/
DESCRIPTION
The LTC2380/LTC2379/LTC2378/LTC2377/LTC2376
low power, low noise ADCs with serial outputs that can
operate from a single 2.5V supply. The following text refers
to the LTC2379-18 but applies to all parts in the family,
the only difference being the maximum sample rates and
the number of bits. The LTC2379-18 supports a ±5V fully
differential input range with a 101dB SNR, consumes
only 18mW and achieves ±2LSB INL max with no miss-
ing codes at 18-bits. The
and AC performance of the LTC2379-18 in conjunction
with the DC590 QuikEval™ and DC718 PScope™ data
collection boards. Use the DC590 to demonstrate DC

LTC2380/LTC2379/LTC2378/
are 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 demonstration circuit 1783A is intended
to demonstrate recommended grounding, component
placement and selection, routing and bypassing for this
ADC. Several suggested driver circuits for the analog
inputs will be presented.
