MCP3905AT-I/SS Description

Short technical summary and product information.

The MCP3905AT-I/SS from Microchip Technology is an energy metering integrated circuit designed for single-phase residential energy metering applications. It supports international energy metering specifications, including IEC 62053.

 

This IC incorporates two 16-bit Delta-Sigma Analog-to-Digital Converters (ADCs) for accurate power measurement. It offers a typical measurement error of 0.1% over specified dynamic ranges. The device includes a programmable gain amplifier (PGA) with selectable gain ratios of 16:1 or 32:1, suitable for low shunt current sensor inputs. An ultra-low drift on-chip reference with a typical drift of 15 ppm/°C ensures stability.

 

The MCP3905AT-I/SS operates over an industrial temperature range of -40°C to +85°C and an extended range of -40°C to +125°C. It is supplied in a 24-SSOP surface mount package. The device provides outputs proportional to active real power, useful for meter calibration and operation.

 

Key electrical characteristics include a typical supply current of 4 mA and an operating voltage of 2.4V. The input impedance is rated at 390 kOhm. This IC is designed for high field reliability in energy metering systems.
