ADEMA124/ADEMA127 24-Bit Sigma-Delta ADCs

Analog Devices Inc. ADEMA124/ADEMA127 24-Bit Sigma-Delta ADCs are 4-channel and 7-channel, respectively, simultaneously sampling analog-to-digital converters (ADCs) designed for polyphase and split-phase energy metering applications. These devices are compatible with voltage dividers, shunts, and isolated current sensors such as current transformers and Rogowski coils. Each ADC channel includes independent hardware and DSP filters that enable gain, phase, and offset compensation. Additionally, the converters feature specialized DSP capabilities, including an integrator and second-order high-pass filter, which simplify Rogowski sensor implementations. Preloaded DSP filter coefficients for common use cases are provided and can be customized to meet specific requirements.
