The 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 1 MSPS throughput rate. They feature 4.5 mW max power and are suitable for battery powered systems, personal digital assistants, medical instruments, mobile communications, instrumentation and control systems, data acquisition systems and optical sensors applications.
The AD7475 and AD7495 are 12‑bit, high‑speed, low‑power 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 a low‑noise track‑and‑hold amplifier, on‑board 2.5 V reference (AD7495), and multiple serial interfaces (SPI, QSPI, Microwire, DSP‑compatible).
The datasheet provides detailed specifications, timing diagrams, operating modes, power‑down options, package dimensions, and ordering information for both devices.
