LTC2374/LTC2373/LTC2372

16-Bit/18-Bit, 1.6Msps/1Msps/500ksps

8-Channel, SAR ADCs

DESCRIPTION

Demonstrationcircuit2071AfeaturestheLTC^®2373family.

TheLTC2374/LTC2373/LTC2372arelownoise,highspeed,

8-channel, 16-/18-bit successive approximation register

(SAR) ADCs. The following text refers to the LTC2373-18

but applies to all parts in the family, the only differences

being the number of bits and the maximum sample rate.

Operating from a single 5V supply, the LTC2373-18 has a

highly configurable, low crosstalk, 8-channel input multi-

plexer,supportingfullydifferential,pseudo-differentialuni-

polar and pseudo-differential bipolar analog input ranges.

performance such as peak-to-peak noise and DC linearity.

Use the DC890 if precise sampling rates are required or to

demonstrate AC performance such as SNR, THD, SINAD

and SFDR. The demonstration circuit 2071 is intended to

demonstraterecommendedgrounding,componentplace-

ment and selection, routing and bypassing for this ADC.

Several suggested driver circuits for the analog inputs

will be presented.
