AD7441/AD7451 are pseudo differential input, 1 MSPS, 10-/12-bit ADCs in an 8-Lead SOT-23 package. The features include fast throughput rate, low power consumption, wide input bandwidth, flexible power/serial clock speed management, high-speed serial interface, etc.
The AD7441 and AD7451 are 10‑/12‑bit successive‑approximation ADCs with a pseudo‑differential input, operating from a single 2.7 V to 5.25 V supply. They deliver up to 1 MSPS throughput while maintaining low power consumption (as low as 4 mW at 3 V).
The document provides detailed specifications, timing diagrams, absolute maximum ratings, pin configurations, and ordering guide information for both the 8‑lead SOT‑23 and MSOP packages. It also includes functional block diagrams and application notes for transducer interfaces, battery‑powered systems, and portable instrumentation.
| Throughput Rate | 1 MSPS max |
