The AD4115 is a low power, low noise, 24-bit, sigma-delta (Σ-Δ) analog-to-digital converter (ADC) that integrates an analog front end (AFE) for eight fully differential or 16 single-ended, high impedance (≥1 MΩ), bipolar, ±10 V voltage inputs.
The AD4115 integrates key analog and digital signal conditioning blocks to configure eight individual setups for each analog input channel in use. The AD4115 features a maximum channel scan rate of 24,845 kSPS (40.25 µs) for fully settled data.
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 different filter settings depending on the requirements of each channel in the application. The automatic channel sequencer enables the ADC to switch through each enabled channel.
The precision performance of the AD4115 is achieved by integrating the proprietary iPassives® technology from Analog Devices, Inc. The AD4115 is factory calibrated to achieve a high degree of specified accuracy.
The AD4115 operates with a single power supply that allows simplified use in galvanically isolated applications. The specified operating temperature range is −40°C to +105°C. The AD4115 is housed in a 40-lead, 6 mm × 6 mm LFCSP.

Evaluation Kits (1)
The EVAL-AD4115SDZ is a full featured evaluation board that can evaluate all features of the AD4115. The AD4115 is a 24-bit, 125 kSPS, Σ-Δ analog-to-digital converter (ADC) with a ±10 V input voltage range (16 single-ended channels or eight fully differential channels). All channels have on-board overvoltage and overcurrent protection.
The EVAL-AD4115SDZ includes voltage references and power and data insulation and can be connected to the Analog Devices, Inc., system demonstration platform (SDP) hardware. The SDP board provides connection to a PC via a universal serial bus (USB) port and can provide power for the EVAL-AD4115SDZ from the PC USB port.
The AD411x Eval+ evaluation software configures the AD4115 functionality and provides dc time domain analysis in the form of waveform graphs, histograms, and associated noise analysis for ADC performance evaluation.
Full specifications for the AD4115 are available in the AD4115 data sheet, which must be consulted in conjunction with this user guide when working with the EVAL-AD4115SDZ.
