Analog Devices AD9225 12‑Bit 25 MSPS ADC Datasheet
The AD9225 provides a complete monolithic solution for high‑speed data acquisition, offering 12‑bit resolution at up to 25 MSPS with low power consumption (280 mW) from a single 5 V supply. It includes an on‑chip sample‑and‑hold amplifier, voltage reference, and digital correction logic, guaranteeing no missing codes across the full temperature range.
The device supports both differential and single‑ended inputs, features an out‑of‑range indicator, and is pin‑compatible with AD9220‑AD9224 parts. It is offered in 28‑lead SOIC and SSOP packages and can operate with 3 V or 5 V logic families.

Questions answered in these manuals
What supply voltage does the AD9225 require?
The AD9225 operates from a single 5 V analog supply (AVDD) and a separate digital supply (DRVDD) that can be 3 V to 5 V.
Does the AD9225 guarantee no missing codes?
Yes, the device guarantees no missing codes over the full temperature range, providing true 12‑bit accuracy.
What is the maximum sampling rate of the AD9225?
The AD9225 can operate at a maximum conversion rate of 25 MSPS (25 MHz).
Does the AD9225 provide an out‑of‑range indicator?
Yes, the OTR output bit signals when the input signal exceeds the converter’s input range.
