MCP3906

Obsolete Device Replacement Device: MCP3905A/MCP3906A MCP3905/06 Energy-Metering ICs with Active (Real) Power Pulse Output Features Supplies active (real) power measurement for single-phase, residential energy-metering Supports the IEC 62053 International Energy Metering Specification and legacy IEC 1036/ 61036/687 Specifications Two multi-bit, Digital-to-Analog Converters (DACs), second-order, 16-bit, Delta-Sigma Analog-to-Digital Converters (ADCs) 0.1% typical measurement error over 500:1 dynamic range (MCP3905) 0.1% typical measurement error over 1000:1 dynamic range (MCP3906) Programmable Gain Amplifier (PGA) for smallsignal inputs supports low-value shunt current sensor - 16:1 PGA - MCP3905 - 32:1 PGA - MCP3906 Ultra-low drift on-chip reference: 15 ppm/°C (typical) Direct drive for electromagnetic mechanical counter and two-phase stepper motors Low IDD of 4 mA (typical) Tamper output pin for negative power indication Industrial Temperature Range: -40°C to +85°C Supplies instantaneous active (real) power on www.DataSheet4U.com HFOUT for meter calibration Description The MCP3905/06 devices are energy-metering ICs designed to support the IEC 62053 International Metering Standard Specification. They supply a frequency output proportional to the average active (real) power, as well as a higher-frequency output proportional to the instantaneous power for meter calibration. They include two 16-bit, delta-sigma ADCs for a wide range of IB and IMAX curre...
