This is 4-layers LTC2991 breakout board used to monitor system temperatures, voltages and currents via I2C 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.

Features:

• Measures Voltage, Current, Temperature
• Measures Four Remote Diode Temperatures
• 0.7°C (Typ) Accuracy, 0.06°C Resolution
• 1°C (Typ) Internal Temperature Sensor
• Series Resistance Cancellation
• 14-Bit ADC Measures Voltage/Current
• PWM Temperature Output
• 3V to 5.5V Supply Operating Voltage
• Eight Selectable Addresses, pre-set to 0x48 via A0-A2 zero resistors
• Internal 10ppm/°C Voltage Reference
• V1 to V8 Inputs ESD Rated to 6kV HBM
