ADS131M06QPBSRQ1

Analog To Digital Converters (ADC) Overview

The ADS131M06QPBSRQ1 is an automotive-grade, six-channel, simultaneous-sampling, 24-bit delta-sigma analog-to-digital converter. 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 a programmable gain amplifier (PGA) with gains from 1 to 128. Key electrical specifications include a typical dynamic range of 102 dB at gain 1 and 80 dB at gain 64. It features a low-drift internal 1.2-V reference, integrated negative charge pump for ground-referenced inputs, and channel-to-channel phase delay calibration. The component is housed in a 32-pin TQFP package.

Analog To Digital Converters (ADC) Feature Summary

• AEC-Q100 qualified for automotive applications across the –40°C to +125°C temperature range
• Six simultaneously sampling differential inputs with independent channel configuration
• Integrated negative charge pump enabling input signals below ground potential
• Programmable channel-to-channel phase delay calibration for sensor response compensation

Analog To Digital Converters (ADC) Applications

• Automotive battery management systems (BMS) including current-shunt measurements
• EV charging stations for DC and AC e-metering
• Energy storage systems (ESS)

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix PBSRQ1 against the manufacturer's official orderable addendum to confirm the tape-and-reel packaging format and quantity. Confirm that the AEC-Q100 qualification grade matches the required automotive temperature range for the target application environment before finalizing procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when simultaneous multi-channel sampling is required for high-precision automotive power monitoring. Ensure the system design accommodates the 2.7 V to 3.6 V supply voltage range and utilizes the integrated 1.2-V reference or external reference as needed. Consider the 32-pin TQFP footprint during PCB layout planning.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS131M06-Q1 family of automotive delta-sigma ADCs. It provides six channels of simultaneous sampling, distinguishing it from lower-channel variants like the ADS131M04-Q1. The Q1 suffix indicates automotive qualification, while the PBSRQ1 designation specifies the 32-pin TQFP package and reel-based shipping configuration.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible alternatives within the same family include the ADS131M06-Q1 non-reel variant. For different channel counts, consider the ADS131M04-Q1 or ADS131M08-Q1, though these require schematic and firmware adjustments due to differing I/O counts.
