ADS130B02QPWRQ1

Analog To Digital Converters (ADC) Overview

The ADS130B02QPWRQ1 is a two-channel, simultaneous-sampling, 16-bit delta-sigma analog-to-digital converter (ADC) designed for automotive applications. It operates with analog and digital supplies ranging from 2.7 V to 3.6 V. The device features programmable data rates up to 32 kSPS and programmable gain settings from 1 to 128. It includes an integrated low-drift 1.2 V internal reference and a precision internal oscillator. The component utilizes a 20-pin TSSOP package and supports an SPI-compatible serial interface.

Analog To Digital Converters (ADC) Feature Summary

• Global-chop mode eliminates offset drift over temperature and time
• Integrated negative charge pump enables input signal measurements below ground
• Optional cyclic redundancy checks (CRCs) maintain communication integrity on data inputs, outputs, and register maps

Analog To Digital Converters (ADC) Applications

• Automotive battery management systems (BMS)
• EV charging stations
• Energy storage systems (ESS)

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix matches the required package type and temperature grade. Confirm that the Q1 designation aligns with AEC-Q100 qualification requirements for your target automotive application. Ensure the pinout corresponds to the 20-pin TSSOP configuration before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when simultaneous sampling of two differential channels is required within an automotive environment. Consider the integrated PGA and internal reference if minimizing external passive components and PCB area is a priority. Evaluate the power consumption modes against the required noise performance and data rate specifications for the specific sensor interface.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS130B04 family, sharing similar architectural features but differing in channel count. While the ADS130B04 offers four channels, the ADS130B02 provides two channels in the same footprint. Both are optimized for cost-sensitive automotive applications requiring high precision and low power consumption.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS130B04QPWRQ1 serves as a direct functional substitute if additional channel capacity is needed without changing the board layout. Verify that the increased channel count does not exceed the system's power budget or SPI bus timing constraints.
