Analog Devices Inc. AD4116 Analog-to-Digital Converters (ADCs)

Analog Devices Inc. AD4116 Analog-to-Digital Converters (ADCs) are low power, low noise, and 24-bit sigma-delta (Σ-Δ) ADCs that integrate the proprietary iPassives® technology for precision performance. These ADCs integrate an Analog Front End (AFE) for six fully differential or eleven single-ended, high-impedance (≥10MΩ) bipolar, and ±10V voltage inputs. The additional two differential or four single-ended/pseudo differential direct ADC inputs provide excellent performance at lower input ranges. The AD4116 ADCs feature a maximum-channel scan rate of 12,422SPS (80µs) using a sinc5 + sinc1 filter and 20,618SPS per channel (48µs) using a sinc3 filter. The AD4116 converters operate with a single power supply and make it easy to use in galvanically isolated applications. These AD4116 ADCs are housed in a 40-lead, 6mm x 6mm LFCSP package.


The AD4116 ADCs’ digital filter allows flexible settings, including simultaneous 50Hz and 60Hz rejection at a 27.27SPS output data rate. The user can select between the different filter settings depending on the demands of each channel in the application. The automatic channel sequencer enables the ADC to switch through each enabled channel. Ideally, these AD4116 ADCs are used in process control, Programmable Logic Controller (PLC) modules, Distributed Control System (DCS) modules, instrumentation, and measurement applications.
