AD9273 is a 8-channel LNA, VGA, AAF, and ADC from Analog Devices, featuring programmable gain and bandwidth.
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.
| Number of channels | 8 |
|---|---|
| Input‑referred noise voltage | 1.26 nV/VHz |
| Sample rate | 10 MSPS to 50 MSPS |
| Power per channel (40 MSPS) | 109 mW |
| Package options | 100‑lead TQFP or 144‑ball BGA |
The maximum single‑ended input voltage is 733 mV p‑p, 550 mV p‑p, or 367 mV p‑p depending on gain settings.
Each channel consumes about 109 mW at a 40 MSPS sample rate.
It is specified for an industrial temperature range of –40 °C to +85 °C.
The device outputs data via a serial LVDS interface compliant with ANSI‑644 and IEEE‑1596.3.
