MCP3905AT-I/SS Energy Metering ICs with Active Real Power Pulse Output

Part Number: MCP3905AT-I/SS

Brand: MICROCHIP

Package: SSOP24

























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 (typ.)
