The Microchip Technology MCP3905A-E/SS is an energy metering integrated circuit designed for single-phase residential energy metering applications. It supports international standards such as IEC 62053 and legacy IEC specifications. The device incorporates two 16-bit Delta-Sigma Analog-to-Digital Converters (ADCs) to accurately measure active real power.
Key electrical specifications include a typical measurement error of 0.1% over a 500:1 dynamic range for the MCP3905A/05L variants. It features a programmable gain amplifier (PGA) with a 16:1 gain for the MCP3905A/05L, supporting low shunt current sensors. An ultra-low drift on-chip reference with a typical drift of 15 ppm/°C ensures stability. The device operates at a typical supply current of 4 mA and requires a 2.4V operating voltage.
Designed for reliability, the MCP3905A-E/SS operates within an extended temperature range of -40°C to +125°C. It is available in a 24-SSOP surface mount package, measuring 0.209 inches (5.30mm) in width. The IC provides outputs proportional to average active real power and instantaneous power for meter calibration, along with a tamper output pin for negative power indication.
