GENERAL DESCRIPTION

The AD4116 is a low power, low noise, 24-bit, Σ-Δ analog-to-

digital converter (ADC) that integrates an analog front end

(AFE) for six fully differential or eleven single-ended, high

impedance (≥10 MΩ) 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 µs) using a sinc5 + sinc1 filter and 20,618 SPS per channel

(48 µs) 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.
