DEMO MANUAL DC2425A

Description

LTC2311/LTC2310

Single 16-Bit/14-Bit/12-Bit,

5Msps/2Msps, Serial,

High Speed SAR ADCs

Demonstrationcircuit2425AfeaturestheLTC®2311family.

Withupto5Msps,thesedifferential,singlechannel,16-bit,

serial, high speed successive approximation register

(SAR) ADCs are available in a 16-lead MSOP package.

The LTC2311 family has an internal 20ppm/°C maximum

drift reference and an SPI-compatible serial interface that

supports CMOS and LVDS logic. Note the demo board is

configured for CMOS operation by default; see the note

under JP3 for LVDS operation. The following text refers

to the LTC2311, but applies to all members of the fam-

ily, the only difference being the sample rate and/or the

number of bits. The DC2425A demonstrates the DC and

AC performance of the LTC2311 in conjunction with the

DC890 PScope™ data collection board. Alternatively, by

connecting the DC2425A into a customer application, the

performance of the LTC2311 can be evaluated directly in

that circuit.
