The AD9280 is a monolithic, single supply, 8-bit, 32 MSPS analog-to-digital converter with an on-chip sample-and-hold amplifier and voltage reference.
The AD9280 is a monolithic, single‑supply, 8‑bit, 32 MSPS analog‑to‑digital converter featuring an on‑chip sample‑and‑hold amplifier, programmable reference, and three‑state digital outputs. It operates from +2.7 V to +5.5 V and consumes only 95 mW at a 3 V supply.
The device is offered in a 28‑lead shrink‑small‑outline package (SSOP) and is pin‑compatible with the AD876‑8, making it suitable for imaging, communications, and instrumentation applications that require low power and high speed.

The AD9280 typically consumes 95 mW at a 3 V supply (110 mW max).
The AD9280 is available in a 28‑lead shrink‑small‑outline (SSOP) package.
Yes, it is pin compatible with the AD876‑8.
The OTR (out‑of‑range) output bit signals an overflow condition when the input exceeds the AD9280’s range.
