ADS7952-Q1

The ADS7952-Q1 is a 12-bit, 10-channel, simultaneous sampling analog-to-digital converter (ADC) designed for high-precision data acquisition in automotive and industrial applications. It features a pipeline architecture that enables rapid conversion rates up to 2 MSPS per channel, ensuring accurate real-time monitoring of multiple analog signals. The device supports simultaneous sampling across all channels, making it ideal for applications requiring synchronized measurements such as motor control, battery management systems, and sensor fusion. This ADC includes an integrated voltage reference, eliminating the need for external reference components and simplifying system design. It operates from a single 3.3 V supply and consumes low power—typically 45 mW at full throughput—making it suitable for power-sensitive environments. The input range is configurable between 0 V to 3.3 V or 0 V to 5 V, offering flexibility in interfacing with various sensor types, including thermocouples, strain gauges, and pressure sensors. The ADS7952-Q1 is qualified to AEC-Q100 Grade 1 standards, ensuring robust performance under harsh automotive conditions, including wide temperature ranges (-40°C to +125°C) and electromagnetic interference. Its serial interface supports both SPI-compatible and I²C communication protocols, enabling seamless integration into existing microcontroller-based systems. Additionally, the device includes built-in diagnostics such as internal self-test and fault detection mechanisms, enhancing system reliability and reducing maintenance overhead. Key features include programmable gain amplifiers (PGAs), which allow scaling of small input signals without external conditioning circuits, and a flexible input multiplexer that allows any of the 10 channels to be selected for conversion. The device also supports continuous and single-shot conversion modes, providing flexibility in data acquisition strategies based on application requirements. Common applications include electric vehicle (EV) battery monitoring, engine control units (ECUs), advanced driver-assistance systems (ADAS), and industrial automation systems where precise, synchronized multi-channel signal acquisition is critical. By combining high speed, accuracy, and automotive-grade reliability, the ADS7952-Q1 delivers a robust solution for demanding measurement tasks in safety-critical and high-performance environments.
