Analog Devices AD9278BBCZ AD9278BBCZ Analogue to Digital Converter 12 bit 65 Msps Differential Single Ended 3 Wire Serial SPI
AD9278 is designed for low cost, low power, small size, and ease of use for medical ultrasound and automotive radar. It contains eight channels of a variable gain amplifier (VGA) with a low noise preamplifier (LNA), an anti aliasing filter (AAF), an analogue-to-digital converter(ADC), and an I/Q demodulator with programmable phase rotation. Each channel features a variable gain range of 45dB, a fully differential signal path, an active input preamplifier termination, and a maximum gain of up to 51dB. 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.
