The AD7482 is a 3Msps 12-bit SAR ADC with fast throughput rate, wide input bandwidth, no pipeline delays, excellent dc accuracy performance, 2 parallel interface modes, low power, single 5V supply operation, internal 2.5V reference, full-scale overrange mode, system offset removal, nominal 0V to 2.5V input and shifted range capability.
The AD7482 is a high‑speed, low‑power 12‑bit successive‑approximation ADC. It offers a parallel interface with up to 3 MSPS throughput and features a built‑in 2.5 V reference, nap and standby power‑saving modes, and a selectable over‑range capability.
The device operates from a 4.75 V‑5.25 V supply, supports a nominal input range of 0 V‑2.5 V (offset‑shiftable), and is housed in a 48‑lead LQFP package suitable for temperatures from –40 °C to +85 °C.
