Description
The DC2531 is the starter kit for demonstrating the per-
formance and ease of use of the
complete temperature measurement system on a chip.
This kit includes the DC2508 (main demo circuit contain-
ing the LTC2986) and the DC2210 (a simple experiment
circuit allowing bread boarding). In addition to the starter
demonstration kit, sensor specific demonstration boards
highlighting the performance of RTDs, thermistors, or
thermocouples are also available.
• Universal Temperature Measurement Board – DC2211
• Thermocouple Board – DC2212
• Dedicated RTD Board – DC2213
• Dedicated Thermistor Board – DC2214

DC2508 and DC2210
The DC2508 is a member of the QuikEval™ family of dem-
onstration boards. It is designed to allow easy evaluation
of the LTC2986 and may be connected to any one of the
sensor daughter boards.
These daughter boards allow evaluation of the various
LTC2986 sensor types (see Figure 1).
For the serial digital interface, the DC2508 may be con-
nected to the DC2026 Linduino™ One.
