ADS1015AQDGSRQ1

Analog To Digital Converters (ADC) Overview

The ADS1015AQDGSRQ1 is a precision, low-power analog-to-digital converter (ADC) from Texas Instruments, designed for automotive applications under the AEC-Q100 qualification standard. It features a 12-bit resolution with a sigma-delta architecture and supports up to 3.3 kSPS sampling rate. The device integrates an internal reference, oscillator, and programmable comparator. It operates on a single supply voltage ranging from 2 V to 5.5 V for both analog and digital domains. The component utilizes an I2C-compatible interface and is available in a compact VSSOP-10 surface-mount package. Key electrical specifications include a gain error of 0.05% FSR and integral nonlinearity (INL) of 0.5 LSB.

Analog To Digital Converters (ADC) Feature Summary

• AEC-Q100 qualified for automotive reliability with operation temperatures from -40°C to +125°C
• 12-bit resolution with 4-channel input capability (differential or single-ended)
• Integrated programmable gain amplifier (PGA), comparator, and oscillator
• Low power consumption with 900 µW typical power dissipation

Analog To Digital Converters (ADC) Applications

• Automotive sensor signal conditioning
• Battery management systems
• Industrial process control monitoring

Analog To Digital Converters (ADC) Procurement Notes

The ADS1015AQDGSRQ1 is listed as obsolete or end-of-life by major distributors such as Mouser. Verification of current availability through authorized Texas Instruments channels or alternative qualified sources is required before procurement planning. Supply chain constraints may affect lead times for remaining stock.

Analog To Digital Converters (ADC) Selection Notes

Select this component when automotive-grade certification (AEC-Q100) is mandatory for the application. Ensure the system voltage aligns with the 2 V to 5.5 V operating range. Consider the VSSOP-10 package dimensions for PCB layout compatibility. Verify that the I2C interface speed and address configuration meet the system bus requirements.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS101x-Q1 family of ultra-small, low-power ADCs. It shares architectural similarities with the ADS1013 and ADS1014 but offers four configurable inputs compared to their single or dual-channel configurations. The 'AQ' suffix denotes automotive qualification, while 'DGSR' indicates the VSSOP-10 package and reel tape packaging format.

Analog To Digital Converters (ADC) Replacement Considerations

For non-automotive applications, the commercial grade ADS1015IDGSR may serve as a functional substitute if AEC-Q100 qualification is not required. For higher channel counts, the ADS1115 series provides 16-bit resolution. Direct pin-to-pin replacements within the same automotive grade require verification of specific suffix variations against current TI product status.
