The MCP3905A-E/SS is a high-performance, fully-integrated analog front-end (AFE) conversion IC component designed for advanced metering infrastructure (AMI) systems, energy monitoring, and power quality analysis applications. This IC offers a wide range of features that enable accurate and reliable measurement of energy parameters. Here is an overview of its key features:
1. Dual Channel: The MCP3905A-E/SS has two independent channels, allowing simultaneous measurements of multiple energy parameters like voltage, current, and power.
2. On-Chip Programmable Gain Amplifier (PGA): It includes an on-chip programmable gain amplifier with a 16-bit gain range, which enables high-resolution measurements across a wide input voltage range.
3. High Sampling Rate: The IC supports a maximum sampling rate of 64 ksps (thousands of samples per second), enabling precise and real-time measurement of energy parameters.
4. Low Offset Voltage and Low-Noise Performance: The MCP3905A-E/SS features low offset voltage and impressive low-noise performance to ensure accurate measurements even in noisy environments.
5. Built-in Calibration: It includes a voltage reference and temperature sensor, which allow on-chip system calibration, eliminating the need for external calibration circuitry.
6. Digital Signal Processing (DSP) Engine: The IC integrates a built-in DSP engine that performs advanced calculations and filtering operations on the measured parameters, reducing the processing load on the host microcontroller
