Introduction: The Core of High-Performance Data Acquisition
In medical imaging, industrial nondestructive testing, and high-energy physics experiments, accurately acquiring faint current signals from hundreds of channels with extremely low noise without sacrificing speed has long been a major challenge for engineers. Analog Devices (ADI)’s ADAS1128BBCZ, a 128-channel, 24-bit current-to-digital analog-to-digital converter, is a revolutionary product designed specifically to address this pain point.
With its high 24-bit resolution, ultra-low noise performance as low as 0.4 fC, and a sampling rate of up to 19.7 kSPS, the ADAS1128BBCZ has become the preferred core component for high-end CT scanners, digital X-ray imaging, and photodiode array monitoring systems.
Currently, as a premium supplier of the ADAS1128BBCZ, Mingjiada Electronics offers genuine, in-stock products, providing robust supply chain support to a wide range of enterprise-level customers.
Key Technical Specifications
The ADAS1128BBCZ is not just an ADC; it is a complete current acquisition solution. It integrates 128 low-power, low-noise integrators, synchronous sample-and-hold circuits, and dual high-speed ADCs onto a single chip.
Channels and Architecture: 128-channel synchronous sampling with no dead time and no charge loss ensures that no signal details are lost in multi-channel systems.
Resolution and Speed: Up to 24-bit resolution and a full-channel throughput of up to 19.7 kSPS (corresponding to a 50.7 μs integration time), perfectly balancing dynamic range and imaging speed.
Ultra-Low Noise: Noise performance as low as 0.4 fC (equivalent to 2,500 electrons), capable of easily detecting extremely weak currents in the pA to fA range, making it ideal for direct connection to photodiodes.
High Precision: Typical integration nonlinearity of ±0.75 ppm and reading accuracy of ±0.025% ensure the accuracy of the data acquired by the system.
Digital Interfaces: Equipped with an LVDS self-clocked serial interface, which significantly reduces external hardware wiring while enabling high-speed data transmission; also supports an SPI configuration interface and allows multiple chips to be daisy-chained, simplifying the design of large arrays.
Application Scenarios
The ADAS1128BBCZ is specifically designed for environments with stringent requirements for accuracy and channel density. Its primary application areas include:
1. Medical Imaging: Data Acquisition Systems (DAS) for CT scanners, digital X-ray, mammography, and medical/dental panoramic X-ray equipment. Its low-noise characteristics help reduce patient radiation exposure while improving image quality.
2. Industrial and Security: Industrial CT inspection, luggage/cargo security scanners, capable of penetrating thicker objects and identifying materials with smaller density differences.
3. Scientific Instruments: Mass spectrometers, X-ray spectrometers, fiber optic power monitoring, and radiation dose measurement systems.
Design Advantages: Why Choose the ADAS1128BBCZ?
For R&D engineers, the appeal of the ADAS1128BBCZ lies not only in its performance specifications but also in its design convenience.
Traditional multi-channel low-current acquisition solutions typically require a complex combination of an “integrator + amplifier + multiplexer + ADC,” which not only occupies a significant amount of PCB space but also introduces additional noise. Through high integration, the ADAS1128BBCZ condenses this complex signal chain into a compact 10mm × 10mm mini-BGA package.
Furthermore, its power consumption is exceptionally low, with a design consuming only approximately 4.5mW per channel. This effectively alleviates thermal management pressures on high-density acquisition boards and enhances the system’s long-term stability.
