GENERAL DESCRIPTION
The AD9272 is designed for low cost, low power, small size, and
ease of use. It contains eight channels of a low noise preamplifier
(LNA) with a variable gain amplifier (VGA), an antialiasing
filter (AAF), and a 12-bit, 10 MSPS to 80 MSPS analog-to-
digital converter (ADC).
Each channel features a variable gain range of 42 dB, a fully
differential signal path, an active input preamplifier termination, a
maximum gain of up to 52 dB, and an ADC with a conversion
rate of up to 80 MSPS. The channel is optimized for dynamic
performance and low power in applications where a small
package size is critical.

The LNA has a single-ended-to-differential gain that is selectable
through the SPI. The LNA input-referred noise voltage is typically
0.75 nV/√Hz at a gain of 21.3 dB, and the combined input-referred
noise voltage of the entire channel is 0.85 nV/√Hz at maximum
gain. Assuming a 15 MHz noise bandwidth (NBW) and a 21.3 dB
LNA gain, the input SNR is about 92 dB. In CW Doppler mode,
the LNA output drives a transconductance amp that is switched
through an 8 × 8 differential crosspoint switch. The switch is
programmable through the SPI.
