AD9261 is a 16-bit, 10 MHz bandwidth, 30 MSPS to 160 MSPS continuous time Sigma-Delta ADC from Analog Devices.
The AD9261 is a 16‑bit continuous‑time sigma‑delta ADC offering 10 MHz input bandwidth and selectable output data rates from 30 MSPS to 160 MSPS. It features an integrated PLL clock multiplier, on‑chip voltage reference, decimation filters and supports offset binary, Gray code or two‑s complement data formats via an SPI interface.
The device operates from a single 1.8 V analog supply and a 1.8 V‑to‑3.3 V digital supply, consuming 375 mW. It is supplied in a 48‑lead LFCSP package and is rated for industrial temperature range (‑40 °C to +85 °C). Typical applications include data acquisition, automated test equipment, instrumentation and medical imaging.
