ADFS7124-4BBCPZ

Analog To Digital Converters (ADC) Overview

The ADFS7124-4 is a low power, 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 inputs or seven single-ended or pseudo differential inputs. The on-chip low gain stage ensures that signals of small amplitude can be interfaced directly to the ADC. One of the major advantages of the ADFS7124-4 is that it gives the flexibility to employ one of three integrated power modes. The current consumption, range of output data rates, and RMS noise can be tailored with the power mode selected. The device also offers a multitude of filter options, ensuring the highest degree of flexibility.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct package type and temperature rating. Confirm functional safety certification requirements align with project specifications. Check for any recent revision updates that may affect pin compatibility or electrical characteristics before finalizing procurement.

Analog To Digital Converters (ADC) Selection Notes

Select the appropriate power mode based on the required balance between RMS noise, output data rate, and current consumption. Ensure the programmable gain amplifier settings match the input signal amplitude to maximize resolution. Verify that the internal reference drift meets the system accuracy requirements over the operating temperature range.

Analog To Digital Converters (ADC) Part Context

The ADFS7124-4 belongs to the Analog Devices ADFS7124 family of precision analog front ends. It shares architectural similarities with other high-resolution sigma-delta converters but distinguishes itself through integrated functional safety features and multiple configurable power modes designed for industrial sensor interfaces.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements within the same family include variants with different channel counts or package options. Verify pinout compatibility and register mapping when substituting with other members of the ADFS7124 series or similar high-precision ADCs from Analog Devices.
