GXSC ADC Replaces AD9245 in New Energy Aging Equipment

New energy aging test equipment is a system used to rapidly test the aging performance of products under various conditions, thereby obtaining their anti-aging characteristics. It can be utilized for product research, development, and quality control. The equipment consists of load modules, acquisition modules, control modules, and simulation modules. During operation, the acquisition system continuously monitors parameters such as product output voltage, load current, real-time power consumption, and temperature throughout the entire process, recording failure characteristics including parameter drift, fluctuation anomalies, overtemperature limit exceedance, and stability degradation, providing data for product screening and quality rating.

New energy product aging is a slow, long-term test that requires an analog-to-digital converter with high precision, high speed, and high stability in sampling characteristics. This solution employs GXSC‘s industrial-grade 14-bit high-speed pipeline analog-to-digital converter. The chip is manufactured using CMOS technology and incorporates a high-performance sample-and-hold amplifier and voltage reference. It is packaged in a plastic QFN32 and can directly replace the AD9245 in a pin-to-pin manner. It is widely used in communications, medical, and industrial applications.

The GXSC ADC features wide bandwidth, excellent dynamic performance, and low power consumption, perfectly balancing the performance, cost, and integration requirements of SDR systems, making it the preferred digital solution for mid-to-high-end SDR systems. It includes a high-performance sample-and-hold amplifier and voltage reference. The device uses a differential multi-stage pipeline architecture with output error correction logic to deliver 14-bit accuracy and ensure no missing codes across the full temperature range. The wideband fully differential SHA allows for multiple selectable input ranges and a wide input common-mode range, including single-ended applications.
