Analog Devices AD9273 Datasheet Rev B
The AD9273 integrates eight channels of low‑noise preamplifier, variable gain amplifier, antialiasing filter and a 12‑bit ADC capable of 10 MSPS to 50 MSPS. It offers SPI‑programmable gain, an 8 × 8 differential crosspoint switch for CW Doppler mode, and a serial LVDS data interface.
Designed for compact, low‑power systems, the device is available in 100‑lead TQFP or 144‑ball BGA packages and operates over an industrial temperature range of –40 °C to +85 °C. Typical power consumption is 109 mW per channel at 40 MSPS.
