LTC2991 - Temperature Sensor and Dual Voltage Monitor

General Description

The LTC®2991 is used to monitor system temperatures, voltages and currents.

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.
