Product Overview

DC1785A demonstration board features the LTC2991, a high performance temperature, voltage and current monitor that uses an I2C interface for communication. Through the I2C serial interface, the eight monitors can individually measure supply voltages and can be paired for differential measurements of current sense resistors or temperature sensing transistors. Additional measurements include internal temperature and internal VCC. The internal 10ppm reference minimizes the number of supporting components and area required. Selectable address and configurable functionality give the LTC2991 flexibility to be incorporated in various systems needing temperature, voltage or current data. DC1785A QuikEval demonstration boards is designed to allow easy evaluation of the LTC2991 and may be connected directly to the target application’s analog signals while using the DC590 USB Serial Controller board and supplied software to measure performance.
