AD9248BSTZ-40

AD9248BSTZ-40 Description

The AD9248BSTZ-40 from Analog Devices Inc. is a high-performance 14-bit, 40MSPS pipelined analog-to-digital converter (ADC) designed for demanding applications requiring precision and speed. Housed in a 64-pin LQFP package, it features simultaneous sampling capability, supporting two differential or single-ended inputs with a 1:1 sample-and-hold (S/H) to ADC ratio. The device operates with dual supply voltages (analog: 2.7V–3.6V, digital: 2.25V–3.6V), ensuring flexibility in mixed-signal designs. Its pipelined architecture delivers low latency and high throughput, making it ideal for real-time signal processing. The ADC supports external or internal reference options, enhancing design adaptability. Compliant with ROHS3 and REACH standards, it is suited for industrial, medical, and communications applications.
