AD7475/AD7495 are 12-bit, 1 MSPS ADCs with features such as fast throughput rate, low power consumption, and wide input bandwidth. They are suitable for battery-powered systems, personal digital assistants, medical instruments, mobile communications, instrumentation and control systems, and data acquisition systems.
The AD7475 and AD7495 are 12‑bit successive‑approximation analog‑to‑digital converters that operate from a single 2.7 V to 5.25 V supply and deliver up to 1 MSPS throughput. They feature low power consumption, a wide input bandwidth, and flexible serial‑interface options such as SPI, QSPI, Microwire and DSP‑compatible modes.
The document lists detailed electrical specifications, absolute maximum ratings, pin‑out diagrams, operating modes (normal, partial and full power‑down), timing characteristics, and example interfacing circuits for a variety of microprocessors and DSPs. It also includes performance curves and recommended layout guidelines.
