ADS131M06IPBS

Analog To Digital Converters (ADC) Overview

The ADS131M06IPBS is a six-channel, simultaneously-sampling, 24-bit delta-sigma analog-to-digital converter (ADC) from Texas Instruments. It operates with analog and digital supply voltages 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 via an integrated low-noise PGA. Key performance metrics include a signal-to-noise ratio of 101 dB at gain 1 and 80 dB at gain 64, with a total harmonic distortion of -100 dB. 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) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current orderable addendum to confirm package type and tape/reel specifications. Ensure that the procurement documentation matches the exact part number variant required for the intended application environment. Cross-reference thermal and electrical specifications with the latest datasheet revision to account for any updates in manufacturing parameters or testing conditions.

Analog To Digital Converters (ADC) Selection Notes

Select this component when high-precision energy metering requires simultaneous sampling across multiple channels. The integrated 1.2-V reference and programmable gain amplifier simplify front-end design by reducing external component count. Consider the available power modes, including very-low-power and current-detect options, if system efficiency or tamper detection features are critical requirements for the target application.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADS131M series of precision analog-to-digital converters designed specifically for metrology applications. It shares functional similarities with other members like the ADS131M08 and ADS131M04 but is distinguished by its six-channel architecture. The series utilizes sigma-delta modulation to achieve high resolution and dynamic range suitable for accurate power measurement tasks.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes within the same family include the ADS131M08 for eight-channel requirements or the ADS131M04 for four-channel configurations. Verify pin compatibility and software register mapping before swapping between these variants to ensure seamless integration without hardware redesign.
