The AD7124-4 and AD7124-8 incorporate a fully integrated signal chain with a 24-bit sigma-delta A/D converter, programmable gain amplifier (PGA), precision reference, reference buffers, current sources, temperature sensor and excitation sources on a single chip. Integrated diagnostic features support SIL compatibility and reduce the need for discrete diagnostic components saving valuable PCB area.
The AD7124-4 and AD7124-8 offer three user-selectable power modes that allow system designers to optimize throughput rate versus required noise performance. In the lowest power mode (255 µA) the converter delivers 21.7 noise free bits at low sampling rates. The user-selectable power modes allow designers of programmable-logic controllers, process controllers, transmission systems and other industrial and instrumentation equipment to develop a single platform by precisely matching power/performance requirements for each use case.
