ADS130B04-Q1

The ADS130B04-Q1 is a high-precision, low-power, 24-bit analog-to-digital converter (ADC) designed for automotive and industrial sensor applications. It features four independent, simultaneous input channels with a programmable gain amplifier (PGA) per channel, enabling accurate measurement of small differential signals from various sensors such as strain gauges, pressure transducers, and temperature probes. This device operates with a supply voltage range of 3.0 V to 5.5 V and consumes only 1.8 mW per channel at 1 kSPS, making it ideal for power-sensitive systems. The ADC supports data rates up to 16 kSPS per channel, offering flexible throughput options tailored to application needs. Its integrated PGA provides gain settings from 1 to 128, allowing direct interface with low-level sensor outputs without external signal conditioning. The ADS130B04-Q1 includes advanced on-chip diagnostics, such as internal self-test, sensor fault detection, and digital filter calibration, ensuring reliable operation in harsh environments. It also supports both synchronous and asynchronous serial communication via a standard SPI-compatible interface, simplifying integration into existing microcontroller-based systems. Designed to meet AEC-Q100 Grade 1 qualification standards, the device is suitable for demanding automotive applications including battery management systems, engine control units, and telematics. Its robust performance under electromagnetic interference (EMI), wide operating temperature range (-40°C to +125°C), and high common-mode rejection ratio (CMRR > 100 dB) ensure consistent accuracy across varying conditions. Additionally, the chip features a built-in reference buffer and low-noise design, minimizing external component count while maintaining excellent signal integrity. The flexible configuration through register programming allows users to optimize performance for specific use cases, such as noise reduction, power savings, or faster response times. The device’s architecture supports both continuous and burst mode operations, enhancing system flexibility in real-time monitoring scenarios. With its combination of high resolution, low power consumption, and automotive-grade reliability, the ADS130B04-Q1 serves as an efficient solution for precision sensing in safety-critical and energy-constrained environments.
