Grouped the ADS1256IDBT pins from the TI datasheet and updated each terminal with a single non-overlapping Pin Group, plus corrected Pin Type and Pin Description.
Applied groups:
  • Power: AVDD, DVDD
  • Ground: AGND, DGND
  • Reference: VREFP, VREFN
  • Analog: AINCOM, AIN0–AIN7
  • Control Bus: ~SYNC/~PDWN, ~RESET
  • SPI: ~CS, SCLK, DIN, DOUT, ~DRDY
  • Oscillator: XTAL1/CLKIN, XTAL2
  • GPIOA: D0/CLKOUT, D1, D2, D3
Verified all 28 pins now have exactly one functional group; no pin was duplicated across groups.

I’ll simplify the pin groups to broader categories while keeping each pin in only one group, then verify the update.

Updated the ADS1256IDBT pin groups to broader functional categories with no duplicates:
  • Power: AVDD, DVDD, AGND, DGND
  • Analog: VREFP, VREFN, AINCOM, AIN0–AIN7
  • Digital: control, SPI, clock/oscillator, and GPIO pins
Verified all 28 terminals now use these general groups while keeping their individual pin descriptions intact.

    The ADS1256IDBT is a high-precision, low-noise, 24-bit analog-to-digital converter manufactured by Texas Instruments. It is designed for high-resolution measurement applications requiring exceptional accuracy, low drift, and programmable data rates. The device integrates a low-noise programmable gain amplifier, a precision delta-sigma ADC core, and a flexible multiplexer that supports multiple differential or single-ended analog inputs.
    The converter is optimized for industrial process control, sensor measurement, weigh scales, data acquisition systems, temperature monitoring, and portable instrumentation. Its integrated digital filtering and selectable gain settings enable direct interfacing with low-level sensors such as strain gauges, thermocouples, RTDs, and bridge sensors without requiring extensive external signal conditioning.
    The ADS1256IDBT supports SPI-compatible serial communication and operates with low power consumption while maintaining excellent dynamic performance and high effective resolution. The device provides programmable output data rates suitable for both low-speed precision measurements and higher-speed acquisition systems.
    Device Features 24-bit delta-sigma analog-to-digital converter Low-noise programmable gain amplifier Eight single-ended or four differential analog input channels Programmable gain settings from 1 to 64 Programmable data output rates SPI-compatible serial interface Integrated digital filter for noise reduction Low offset drift and gain drift Internal oscillator support Sensor burnout detection capability Self-calibration and system calibration functions Low power operation Wide analog supply voltage range Excellent 50 Hz and 60 Hz rejection performance Electrical Characteristics Resolution of 24 bits Maximum data rate up to 30 kSPS Differential input architecture Input multiplexer for multi-channel acquisition Low RMS noise performance High common-mode rejection ratio High power-supply rejection ratio Programmable gain amplifier integrated on-chip Internal reference support with external reference capability Interface and Control SPI-compatible digital communication interface Configurable control registers Read and write register functionality Synchronization and standby control support Hardware reset capability Interrupt and data-ready signaling support Package Information Manufacturer package designation: DBT Package type: TSSOP Surface-mount device Fine-pitch lead configuration Industrial temperature grade device Applications Precision data acquisition systems Industrial automation and control Weigh scales and bridge sensors Temperature measurement systems Pressure sensing applications Portable instrumentation Medical instrumentation Laboratory measurement equipment Energy monitoring systems Process monitoring and control Manufacturer Information Manufacturer: Texas Instruments Manufacturer Part Number: ADS1256IDBT Product Category: Precision Analog-to-Digital Converter RoHS compliant device
