ADS131E04IPAG

Analog Front End (AFE) Overview

The ADS131E04IPAG is a Texas Instruments analog front-end (AFE) featuring four simultaneous-sampling, 24-bit delta-sigma analog-to-digital converters. It integrates programmable gain amplifiers, an internal reference voltage source, and an on-board oscillator within a TQFP-64 package. The device supports data rates up to 64 kSPS with a dynamic range of 118 dB at 1 kSPS. It operates on a 2.7 V to 5.25 V analog supply and a 1.8 V to 3.6 V digital supply, functioning reliably across a temperature range of -40°C to +105°C.

Analog Front End (AFE) Feature Summary

• Four-channel simultaneous sampling with 24-bit resolution
• Integrated PGA, internal reference, and oscillator
• SPI interface with fault detection capabilities
• Low power consumption of 6 mW typical

Analog Front End (AFE) Applications

• Industrial power monitoring and protection
• Energy metering systems
• Battery test equipment
• Industrial process control

Analog Front End (AFE) Procurement Notes

Verify the specific suffix 'PAG' confirms the TQFP-64 surface-mount package and lead-free composition. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to procurement. Ensure the ordering part number matches the required channel count and package type for the design.

Analog Front End (AFE) Selection Notes

Select this component when four synchronized high-resolution channels are required for power applications. Verify that the input signal range aligns with the integrated PGA settings of 1, 2, 4, 8, or 12. Ensure the system clock configuration supports the desired data rate up to 64 kSPS. Check compatibility with the host microcontroller's SPI interface and GPIO requirements for DRDY signaling.

Analog Front End (AFE) Part Context

This part belongs to the ADS131E0x family, which includes variants with different channel counts such as the ADS131E06 and ADS131E08. All members share the same core architecture, pinout, and functionality, differing primarily in the number of available ADC inputs. This specific model provides four differential ADC inputs suitable for compact multi-phase metering designs.

Analog Front End (AFE) Replacement Considerations

Direct substitutes within the same family include the ADS131E06IPAG and ADS131E08IPAG, which offer six and eight channels respectively while maintaining identical electrical characteristics and pinouts. Other TI AFEs may require schematic and firmware modifications due to pin or feature differences.
