AD7484 is a 3MSPS, 14-bit SAR ADC with high throughput rate, wide input bandwidth, no pipeline delays, high DC accuracy, low power, single 5V supply, internal 2.5V reference, full-scale overrange mode, system offset removal, 0V to 2.5V input, and shifted range capability
The AD7484 is a high‑speed, low‑power 14‑bit successive‑approximation ADC offering up to 3 MSPS throughput. It features a wide 40 MHz input bandwidth, internal 2.5 V reference, and flexible input range with offset capability. Power modes include normal (90 mW), nap (2.5 mW) and standby (10 µW).
The device is supplied from a 4.75‑5.25 V rail, uses a parallel interface with configurable logic levels, and is housed in a 48‑lead LQFP package. Detailed specifications cover dynamic performance, absolute maximum ratings, pin functions, timing characteristics, and ordering information.
