AD7470/AD7472 is a 1.75 MSPS 10-bit/12-bit parallel ADC with a operating voltage range of 2.7V to 5.25V. It features low power consumption, wide input bandwidth, high-speed parallel interface, etc.
The AD7470 (10‑bit) and AD7472 (12‑bit) are successive‑approximation analog‑to‑digital converters that operate from a single 2.7 V to 5.25 V supply. They provide high‑speed parallel data output, no pipeline delay, and an optional sleep mode for ultra‑low power operation.
Key features include up to 1.75 MSPS (AD7470) or 1.5 MSPS (AD7472) throughput, low typical power consumption (3.54 mW at 1.2 MSPS, 3 V for AD7472), 50 nA sleep‑mode current, and flexible power‑throughput management via an external clock. The devices are offered in 24‑lead SOIC and TSSOP packages and support standard CS, RD, CONVST, and BUSY control signals.
| Maximum Throughput (AD7470) | 1.75 MSPS |
|---|---|
| Maximum Throughput (AD7472) | 1.5 MSPS |
| Typical Power Consumption (AD7472, 3 V, 1.2 MSPS) | 3.54 mW |
| Sleep‑Mode Current | 50 nA typ. |
In sleep mode the device draws as little as 50 nA typical current.
