AD7475/AD7495 are 12-bit high speed, low power, successive-approximation ADCs that operate from a single 2.7 V to 5.25 V power supply with throughput rates up to 1 MSPS.
The AD7475 and AD7495 are 12‑bit successive‑approximation ADCs that operate from a single 2.7 V to 5.25 V supply and achieve up to 1 MSPS throughput. They feature low power consumption, a wide input bandwidth, and multiple serial interfaces (SPI, QSPI, Microwire, DSP‑compatible). The devices include on‑board reference (AD7495) and support standby mode with 1 pA leakage.
The datasheet provides detailed electrical specifications, timing diagrams, pin configurations, operating modes, power‑vs‑throughput curves, and ordering information for both parts. It also includes mechanical outline dimensions for the MSOP and SOIC packages.
