12-Bit/14-Bit, 5Msps/4.5Msps/
2.5Msps/500ksps/Serial,
High Speed SAR ADCs
DESCRIPTION
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.
