Product Details

The DC2420 is the starter kit for demonstrating the performance and ease of use of the LTC2984, which is a complete temperature measurement system on a chip. This kit includes the DC2399 (main demo circuit containing the LTC2984) 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.
