AD9670EBZ Datasheet PDF - ADI

●The AD9670EBZ is an evaluation board for evaluating AD9670 octal ultrasound AFE with digital demodulator. The AD9670 is designed for low cost, low power, small size and ease of use for medical ultrasound. It contains eight channels of a variable gain amplifier (VGA) with a low noise preamplifier (LNA), a CW harmonic rejection I/Q demodulator with programmable phase rotation, an antialiasing filter (AAF), an analog to digital converter (ADC), and a digital demodulator and decimator for data processing and bandwidth reduction. Each channel features a maximum gain of up to 52dB, a fully differential signal path, and an active input preamplifier termination. The channel is optimized for high 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.
