APPLICATIONS MRI receivers Multicarrier, multimode, cellular receivers Antenna array positioning Power amplifier linearization Broadband wireless Radar Infrared imaging munications instrumentation Optional features allow users to implement various selectable operating conditions, including input range, data format select, and output data mode. The AD9460 is available in a Pb-free, 100-lead, surface-mount, plastic package (TQFP_EP) specified over the industrial temperature range of - 40°C to +85°C. PRODUCT HIGHLIGHTS 1. 2. True 16-bit linearity. High performance: outstanding SNR performance for baseband IFs in data acquisition, instrumentation, magnetic resonance imaging, and radar receivers. Ease of use: on-chip reference and high input impedance, track-and-hold with adjustable analog input range, and an output clock simplifies data capture. Packaged in a Pb-free, 100-lead TQFP/EP. Clock duty cycle stabilizer (DCS) maintains overall ADC performance over a wide range of clock pulse widths....
