The MCP3909-I/SS from Microchip Technology is an energy-metering integrated circuit designed for single-phase applications, adhering to the IEC 62053 international standard. This device features two 16-bit delta-sigma ADCs with an 81 dB SINAD typical on both channels. It provides a 0.1% typical active energy measurement error over a 1000:1 dynamic range.
The IC supports digital waveform data access through an SPI interface, outputting 16-bit ADC data words and a 20-bit multiplier output word. It includes an ultra-low drift on-chip voltage reference with a typical drift of 15 ppm/°C. The device is suitable for small shunt current sensor designs and can directly drive electromagnetic mechanical counters and two-phase stepper motors.
Packaged in a 24-SSOP, the MCP3909-I/SS is designed for surface mounting. It operates within an industrial temperature range of -40°C to +85°C. The device also features a tamper output pin for negative power indication and a low supply current of 4 mA maximum.
