AD4110-1 Universal Input AFE with 24-Bit ADC

Analog Devices Inc. AD4110-1 Universal Input AFEs with 24-bit ADC are complete, single-channel, universal input analog-to-digital front ends for industrial process control systems that require sensor type flexibility. The high voltage input is fully software configurable for current or voltage signals. It enables direct interface to all standard industrial analog signal sources and all thermocouple types. Field power can be supplied for loop-powered current output sensors. The modules include a range of excitation current sources for resistance-temperature detector (RTD) sensors and other resistive sensors. The integrated, fully differential programmable gain amplifier (PGA) offers 16 gain settings from 0.2 to 24. Analog Devices Inc. AD4110-1 Universal Input AFEs incorporate a precision 24-bit, Σ-Δ, analog-to-digital converter (ADC) and come in a 40-lead, 6mm x 6mm LFCSP package.
