ANALOG DEVICES AD9674KBCZ

AD9674 is an octal ultrasound analogue front end. It is designed for low cost, low power, small size and ease of use for medical ultrasound. It contains eight channels of a VGA with an LNA, a CW harmonic rejection I/Q demodulator with programmable phase rotation, an AAF, an ADC, a digital HPF, and RF decimation by 2. 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 serial port interface (SPI). Application includes medical imaging/ultrasound, non-destructive testing (NDT).
