AD9278BBCZ

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.

• 8 channels of LNA, VGA, AAF, ADC, and I/Q demodulator

• Analog-to-digital converter (ADC) SNR:65dBFS at fIN = 5MHz at -10dBFS, GAIN+ = 0V
• Serial LVDS (ANSI-644, low power/reduced signal)
• 144 lead CSPBGA package
• Operating temperature range from -40 to 85°C
