ADFS7124-8BBCPZ

Analog To Digital Converters (ADC) Overview

The ADFS7124-8 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 8 differential inputs or 15 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 ADFS7124-8 is that it gives the user 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 official Analog Devices documentation to confirm package type, temperature range, and functional variants. Ensure compatibility with system voltage requirements and interface standards before procurement. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Analog To Digital Converters (ADC) Selection Notes

Select the appropriate power mode based on required output data rate and noise performance. Consider the number of channels needed and whether differential or single-ended inputs are required. Evaluate the need for internal versus external reference sources and clock configurations. Check diagnostic requirements for safety integrity level certification.

Analog To Digital Converters (ADC) Part Context

The ADFS7124-8 belongs to the AD7124 family of sigma-delta ADCs from Analog Devices. It shares core architecture with other members but offers specific channel counts and feature sets tailored for high-precision industrial applications. It integrates PGA, reference, and extensive diagnostics into a single package.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements within the AD7124 family include the AD7124-4 for fewer channels or the ADUC7124 series if an integrated microcontroller is required. Verify pinout compatibility and register map similarities when substituting.
