Microchip Technology MCP3906A
Energy Metering IC
FEATURES
● Supplies active (real) power measurement for single-phase, residential energy metering● Supports IEC 62053 International Energy Metering Specification and legacy IEC 1036/61036/687 Specifications
● Two multi-bit, DAC, second-order, 16-bit, DeltaSigma Analog-to-Digital Converters (ADCs)
● Reduced pulse-width of calibration output frequency and mechanical counter drive for low power meter designs (MCP3905L)
● Increased output frequency constant options for meter design (MCP3905L)
● 0.1% typical measurement error over 500:1 dynamic range (MCP3905A / MCP3905L)
● 0.1% typical measurement error over 1000:1 dynamic range (MCP3906A)
● Programmable Gain Amplifier (PGA) for small signal inputs supports low value shunt current sensor: - 16:1 PGA - MCP3905A / MCP3905L - 32:1 PGA - MCP3906A
● Ultra-low drift on-chip reference: 15 ppm/°C (typical)
● Direct drive for electromagnetic mechanical c
