AD7476A/AD7477A/AD7478A is 1 MSPS, 12-/10-/8-bit ADCs, operating voltage is 2.35 V to 5.25 V, low power consumption, wide input bandwidth, support SPI®/QSPI™/MICROWIRE™/DSP compatible high-speed serial interface.
The AD7476A/AD7477A/AD7478A family provides high‑speed, low‑power analog‑to‑digital conversion in 6‑lead SC70 and 8‑lead MSOP packages. They operate from a single 2.35 V to 5.25 V supply and achieve up to 1 MSPS throughput with a fast, pipeline‑free conversion process.
These converters are suited for battery‑powered systems, PDAs, medical instruments, mobile communications, instrumentation, data‑acquisition, high‑speed modems, and optical sensors. Automotive‑qualified versions are also offered, meeting the reliability requirements of automotive applications.
