The ADX3224/ADX3226/ADX3228 are a series of multi-channel, simultaneous sampling, 24-bit, ΔΣ analog-to-digital converters (ADC) with an integrated programmable gain amplifier (PGA), internal reference, and an on-board oscillator. The ADC's wide dynamic range, scalable data rates, and internal fault detection monitors make the ADX3224/ADX3226/ADX3228 highly attractive for industrial power monitoring and protection as well as test and measurement applications. True high-impedance inputs enable the ADX3224/ADX3226/ADX3228 to directly connect with resistor divider networks or voltage transformers to measure line voltages, or with current transformers or Rogowski coils to measure line currents. The ADX3224/ADX3226/ADX3228 series features high integration and superior performance, capable of creating scalable industrial power systems with significantly reduced size, power consumption, and lower overall costs. Each channel of the ADX3224/ADX3226/ADX3228 has a flexible input multiplexer that can independently connect to internally generated signals for testing, temperature sensing, and fault detection. Fault detection can be implemented within the device using integrated comparators with DAC-controlled trigger levels.The ADX3224/ADX3226/ADX3228 can operate at data rates up to 64kSPS. These complete analog front-end (AFE) solutions come in a QFP-64 package and are rated for an industrial temperature range of -40°C to 105°C.
