Description

The AD4116 is a low power, low noise, 24-bit, ?-? analog-to-digital converter (ADC) that integrates an analog front end (AFE) for six fully differential or eleven single-ended, high impedance (?10 M?) bipolar, ?10 V voltage inputs. The additional two differential or four single-ended/pseudo differential direct ADC inputs provides excellent performance at lower input ranges.The AD4116 also integrates key analog and digital signal conditioning blocks to configure eight individual setups for each analog input channel in use. As many as 16 channels can be enabled at any time. A channel is defined as any of the standard analog voltage inputs or a low level direct ADC input. The AD4116 features a maximum channel scan rate of 12,422 SPS (80 ?s) using a sinc5 + sinc1 filter and 20,618 SPS per channel (48 ?s) using a sinc3 filter.The embedded 2.5 V, low drift (5 ppm/?C), band gap internal reference (with output reference buffer) reduces the external component count.The digital filter allows flexible settings, including simultaneous 50 Hz and 60 Hz rejection at a 27.27 SPS 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.The precision performance of the AD4116 is achieved by integrating the proprietary iPassives? technology from Analog Devices, Inc.The AD4116 operates with a single power supply, making it easy to use in galvanically isolated applications. The specified operating temperature range is ?40?C to +105?C. The AD4116 is housed in a 40-lead, 6 mm ? 6 mm LFCSP.APPLICATIONS Process control PLC and DCS modules Instrumentation and measurement
