Product Details
| DESCRIPTION The LTC® 2945 is a rail-to-rail system monitor that measures current, voltage, and power. It features an operating range of 2.7V to 80V and includes a shunt regulator for supplies above 80V to allow flexibility in the selection of input supply. The current measurement range of 0V to 80V is independent of the input supply. An onboard 0.75 accurate 12-bit ADC measures load current, input voltage and an auxiliary external voltage. FEATURES Rail-to-Rail Input Range: 0V to 80V Wide Input Supply Range: 2.7V to 80V Shunt Regulator for Supplies >80V Δ∑ ADC with less than ±0.75 Total Unadjusted Error 12-Bit Resolution for Current and Voltages nternal Multiplier Calculates 24-Bit Power Value Stores Minimum and Maximum Values Additional ADC Input Monitors an External Voltage nternal Digital Multiplier Calculates Power Continuous Scan and Snapshot Modes Shutdown Mode with IQ< 80μA Split SDA for Opto-Isolation Available in 12-Lead 3mm ×3mm QFN and MSOP Packages APPLICATIONS Telecom Infrastructure Industrial Automotive Consumer |
