The AD4195-4 is a low noise, completely integrated analog front end for high precision measurement applications. The device contains a low noise, 24-bit Σ-Δ analog-to-digital converter (ADC) and can be configured to have four differential or eight single-ended or pseudodifferential inputs. The on-chip low-noise gain stage ensures that signals of small amplitude can be interfaced directly to the ADC.
Please see the data sheet for the full description.
