The AD4113 is a low power, low noise, 16-bit, Σ-Δ analog-to-digital converter (ADC) that integrates an analog front end (AFE) for four fully-differential or eight single-ended inputs.
The precision performance of the AD4113 is achieved by integrating the proprietary iPassives™ technology from Analog Devices, Inc. The AD4113 has high impedance (≥1MΩ) and can accommodate ±10V true bipolar voltage inputs at a maximum channel scan rate of 24.845kSPS (40.25μs) for fully settled data. The output data rates range from 2.5SPS to 125,000SPS.
The AD4113 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 being defined as any of the standard analog voltage input. The embedded 2.5V (5ppm/°C) band gap internal reference (with output reference buffer) reduces the external component count.
The digital filter allows flexible settings, which include 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.
The AD4113 operates with a single 5V power supply, which makes the device easy to use in galvanically isolated applications. The specified operating temperature range is −40°C to +105°C. The AD4113 is housed in a 40-lead, 6mm × 6mm LFCSP.
