ADS131E06 Replacement: GX131E06 Pin-to-Pin 6-Channel 24-Bit ADC

GX131E06 is developed for industrial power monitoring, protection, test and measurement, and simultaneous-sampling data acquisition systems.

Its six high-impedance input channels can interface with resistor-divider networks or voltage transformers for line-voltage measurement and with current transformers or Rogowski coils for current measurement.

The QFP64 version is designed for pin-to-pin hardware replacement of ADS131E06, allowing the existing QFP64 PCB footprint and pin routing to be retained. An optional BGA64 package is available for new designs requiring a smaller board footprint.

GX131E06 as a Pin-to-Pin ADS131E06 Replacement

GX131E06 integrates six simultaneous-sampling 24-bit delta-sigma ADC channels with programmable gain amplifiers, an internal voltage reference and an onboard oscillator.

The device supports output data rates from 250 SPS to 64 kSPS and programmable gains of 1, 2, 3, 4, 6, 8, 12 and 24. The additional low-data-rate and gain settings provide greater flexibility for measuring signals with different amplitudes and bandwidth requirements.

For existing ADS131E06-based equipment, the GX131E06 QFP64 package provides a pin-to-pin hardware migration path without redesigning the PCB footprint. GX131E06 is also suitable for new multichannel measurement and protection systems.

Pin-to-Pin QFP64 Hardware Compatibility and SPI Interface

The GX131E06 QFP64 version is designed around the ADS131E06 pin configuration. Existing analog-input connections, power connections, reference circuitry, clock and synchronization signals, GPIO connections and SPI signal routing can be retained.

The SPI interface supports communication with MCUs, DSPs and FPGAs. Four GPIO pins, synchronization control and daisy-chain operation simplify the implementation of multi-device systems requiring additional measurement channels.

The 8 mm × 8 mm BGA64 package provides the same six-channel conversion architecture in a smaller package for space-constrained new designs.

GX131E06 vs ADS131E06: Key Specification Comparison

GX131E06 retains the principal channel count, resolution, maximum data rate, supply ranges and system-control functions of ADS131E06 while providing additional gain settings, a 250 SPS operating mode and improved specified dynamic performance.
