DEMO MANUAL DC1563A

DESCRIPTION

LTC2315/LTC2314/LTC2313/LTC2312/

12-Bit/14-Bit, 5Msps/4.5Msps/

2.5Msps/500ksps/Serial,

High Speed SAR ADCs

Demonstration circuit 1563A features the LTC®2315

family. With sample rates up to 5Msps these unipolar,

single channel, 12-/14-Bit, serial, high speed successive

approximation register (SAR) ADCs are available in an

8-lead TSOT package. The LTC2315 family has an internal

20ppm reference and an SPI-compatible serial interface

that supports 1.8V, 2.5V, 3V and 5V logic. The following

text refers to the LTC2315 but applies to all members of

the family, the only difference being the sample rate and

the number of bits. The DC1563A demonstrates the DC

and AC performance of the LTC2315 in conjunction with

the DC590 QuikEval™ and the DC718 PScope™ data

collection boards. Use the DC590 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. Alternatively, by connecting the DC1563A into

a customer application the performance of the LTC2315

can be evaluated directly in that circuit.
