Analog Devices AD4112 24-Bit Sigma-Delta ADC Data Sheet

The AD4112 is a single-supply, 24-bit sigma-delta ADC that integrates an analog front end (AFE) to support fully differential or single-ended high-impedance bipolar voltage inputs (±10 V) and 0 mA to 20 mA current inputs. It features up to 8 individual setups per channel, including programmable gain, offset calibration, and filtering options such as simultaneous 50 Hz and 60 Hz rejection.

The device operates with a maximum channel scan rate of 6.21 kSPS and includes an embedded 2.5 V low-drift internal reference to reduce external component count. It is housed in a 40-lead, 6 mm × 6 mm LFCSP package and supports SPI, QSPI, MICROWIRE, and DSP-compatible digital interfaces.
