AD7466/AD7467/AD7468 are 1.8V to 3.6V micro-power 8/10/12-bit ADCs with features including low power consumption, fast throughput rate, wide input bandwidth, and compatibility with multiple interfaces. They are suitable for applications such as battery-powered systems, medical instruments, and remote data acquisition.
The AD7466/AD7467/AD7468 family are low‑power successive‑approximation ADCs available in 8‑, 10‑, and 12‑bit versions. They operate from a single 1.8 V to 3.6 V supply and achieve up to 100 kSPS throughput while consuming less than 1 mW in normal mode. The devices are offered in compact 6‑lead SOT‑23 and 8‑lead uSOIC packages.
Key features include a wide input bandwidth, flexible power/clock management, standby mode current of 0.5 pA, and a high‑speed serial interface compatible with SPI, QSPI, I²C, and DSP buses. Typical applications are battery‑powered systems, medical instruments, and isolated data acquisition.
