ADS1013-Q1

The ADS1013-Q1 is a high-precision, low-power 12-bit analog-to-digital converter (ADC) designed for automotive and industrial applications. It features a built-in programmable gain amplifier (PGA) that supports input ranges from ±256 mV to ±6.144 V, enabling flexible signal conditioning without external components. The device operates on a supply voltage range of 2.7 V to 5.5 V, making it suitable for both 3.3 V and 5 V systems commonly found in automotive electronics. This ADC includes an I²C-compatible serial interface for easy integration into microcontroller-based systems, allowing fast data transfer rates up to 400 kHz. It supports four selectable input channels (A0–A3), with a single-ended or differential input configuration, providing versatility in sensor interfacing. The internal reference voltage is stable over temperature and supply variations, ensuring consistent measurement accuracy across different operating conditions. Designed for reliability in harsh environments, the ADS1013-Q1 meets AEC-Q100 Grade 1 qualification standards, making it ideal for use in automotive systems such as battery management, engine control units, and safety-critical sensors. Its low quiescent current—typically 120 µA in continuous conversion mode—makes it energy-efficient for always-on monitoring applications. The device also features configurable conversion modes including single-shot and continuous conversion, along with programmable alert thresholds for interrupt-driven operation. These features reduce host processor load by enabling autonomous triggering of system responses when measurements exceed predefined limits. Additionally, the ADS1013-Q1 offers a comprehensive set of power-saving features, including shutdown mode with less than 1 µA current consumption. With a compact 8-pin SO package and robust EMI immunity, the ADS1013-Q1 is well-suited for space-constrained designs where performance and reliability are critical. Its integrated self-test and diagnostic functions enhance system integrity, particularly in safety-related applications. Overall, this ADC delivers precision, flexibility, and efficiency for demanding real-time analog signal acquisition tasks in automotive and industrial environments.
