ADS131M06IPBSR

Analog To Digital Converters (ADC) Overview

The ADS131M06IPBSR is a six-channel, simultaneously-sampling, 24-bit delta-sigma analog-to-digital converter (ADC) from Texas Instruments. It operates with analog and digital supplies ranging from 2.7 V to 3.6 V. The device supports programmable data rates up to 32 kSPS and offers programmable gain settings from 1 to 128. Key performance metrics include a typical signal-to-noise ratio of 101 dB at gain 1 and 80 dB at gain 64, both measured at 4 kSPS. The integrated low-drift internal voltage reference provides 1.2 V. Power consumption is specified at 4.9 mW under standard operating conditions. The component is housed in a 32-pin TQFP package and functions within an industrial temperature range of –40°C to +125°C.

Analog To Digital Converters (ADC) Feature Summary

• Six differential inputs enable simultaneous sampling for multi-phase or high-precision applications.
• Integrated channel-to-channel phase calibration and offset/gain correction registers reduce signal chain errors.
• Fast startup capability delivers the first valid data conversion within 0.5 ms of supply ramp completion.
• Optional cyclic redundancy checks on communication lines and register maps ensure data integrity.

Analog To Digital Converters (ADC) Applications

• Electricity meters for commercial and residential use
• Circuit breakers and protection relays
• Power quality meters
• Battery test equipment and battery management systems

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current orderable addendum to confirm package type and tape-and-reel specifications. Ensure that the selected variant matches the required thermal and electrical characteristics for the target application environment. Cross-reference the part number with official distributor catalogs to validate availability and lead times prior to finalizing procurement plans.

Analog To Digital Converters (ADC) Selection Notes

Select this component when simultaneous sampling across multiple channels is required for accurate power measurement. Evaluate the input impedance requirements, as high-impedance inputs are available for higher gain settings. Consider the integrated 1.2-V reference if PCB area reduction is a priority. Verify that the SPI interface timing constraints align with the host microcontroller capabilities for reliable data acquisition.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADS131M series of energy metering ADCs. It shares functional similarities with other members like the ADS131M02 and ADS131M08 but is distinct in its six-channel configuration. The IPBSR suffix indicates a specific packaging and reel format within the broader ADS131M06 product family, designed for surface-mount assembly in industrial environments.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes within the same family include the ADS131M02 for two-channel applications and the ADS131M08 for eight-channel requirements. When replacing, verify pin compatibility and software register mapping differences between channel counts. Ensure that the replacement part maintains the required 24-bit resolution and simultaneous sampling capabilities for the existing system design.
