The AD7484 is a 14-bit SAR ADC with a conversion rate of 3 MSPS and an input bandwidth of 40 MHz. It offers fast throughput, excellent DC accuracy, and low power consumption.
The AD7484 is a 14‑bit successive‑approximation ADC offering up to 3 MSPS throughput and a wide 40 MHz input bandwidth. It operates from a single 4.75 V‑5.25 V supply and includes an on‑board 2.5 V reference with offset‑shift capability.
The device provides multiple power‑saving modes (normal, nap at 2.5 mW, and standby at 10 µW) and a parallel interface with configurable logic levels. It is supplied in a 48‑lead LQFP package and is rated for –40 °C to +85 °C operation.
