The AD7476/AD7477/AD7478 are 1 MSPS, 12/10/8-bit ADCs from Analog Devices, available in a 6-lead SOT-23 package. They feature a fast throughput rate, low power consumption, wide input bandwidth, 70 dB SNR, flexible power/serial clock speed management, no pipeline delays, a high speed serial interface, STANDBY mode, and are suitable for applications such as battery-powered systems, personal digital assistants, medical instruments, mobile communications, instrumentation and control systems, data acquisition systems, high speed modems, and optical sensors.
The AD7476, AD7477 and AD7478 are 12‑, 10‑ and 8‑bit successive‑approximation analog‑to‑digital converters offered in a 6‑lead SOT‑23 package. They operate from a single 2.35 V to 5.25 V supply and deliver up to 1 MSPS throughput with low power consumption, making them suitable for battery‑powered and portable applications.
The document lists detailed electrical specifications, timing diagrams, pin configurations, absolute maximum ratings and ordering codes. It also includes functional block diagrams, typical performance curves and application notes for interfacing these ADCs to microprocessors or DSPs.
