ADS131E06IPAG

Analog Front End (AFE) Overview

The ADS131E06IPAG is a Texas Instruments analog front-end (AFE) featuring six synchronous sampling, 24-bit sigma-delta analog-to-digital converters. It integrates programmable gain amplifiers (PGA), 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. Analog supply voltage ranges from 2.7 V to 5.25 V, while the digital supply operates between 1.8 V and 3.6 V. Operating temperatures span from -40°C to +105°C.

Analog Front End (AFE) Feature Summary

• Six differential ADC inputs with independent channel configuration
• Integrated PGA with gains of 1, 2, 4, 8, and 12
• Internal fault detection using integrated comparators and DAC-controlled trigger levels
• Flexible input multiplexer for testing, temperature monitoring, and fault detection

Analog Front End (AFE) Applications

• Industrial power protection systems including circuit breakers and relays
• Single-phase and multi-phase energy metering
• Battery test systems
• Industrial test and measurement equipment

Analog Front End (AFE) Procurement Notes

Verify the specific suffix IPAG confirms the TQFP-64 surface-mount package and industrial temperature rating (-40°C to +105°C). Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets before procurement.

Analog Front End (AFE) Selection Notes

Select this model when six synchronized channels are required for high-precision AC signal acquisition. Ensure the application utilizes differential inputs compatible with the PGA range. Verify that the system clock requirements align with the internal oscillator capabilities or external clock inputs specified in the electrical characteristics.

Analog Front End (AFE) Part Context

This component belongs to the ADS131E0x family of multi-channel AFEs, which also includes the four-channel ADS131E04 and eight-channel ADS131E08 variants. All models share the same 64-pin TQFP footprint and core architecture, differing primarily in the number of available ADC channels to suit varying system complexity.

Analog Front End (AFE) Replacement Considerations

The ADS131E04IPAG and ADS131E08IPAG are direct pin-compatible alternatives within the same series. Selection depends on whether fewer than six or more than six channels are required for the specific design.
