The ADS5521 is a high-performance, 12-bit, 105MSPS analog-to-digital converter (ADC). ADS5521 provides a complete converter solution, including a high-bandwidth linear sample-and-hold stage (S&H) and internal reference. Designed for applications demanding the highest speed and highest dynamic range.
The ADS5521 is a high‑performance 12‑bit analog‑to‑digital converter offering a 105 MSPS sample rate and a 2.3 Vpp differential input range. It operates from a single 3.3 V supply, delivering low analog power dissipation (571 mW) and an output buffer power of 165 mW, making it suitable for space‑constrained, high‑speed applications such as wireless communication, radar, and medical equipment.
The datasheet provides complete electrical, digital, and timing characteristics, absolute maximum ratings, recommended operating conditions, mechanical dimensions, and a three‑wire serial programming interface. It also includes ordering information, package details (TQFP‑64 PowerPAD), and important warranty and usage notices.
