APPLICATIONS MRI receivers Multicarrier, multimode, cellular receivers Antenna array positioning Power amplifier linearization Broadband wireless Radar Infrared imaging Communications instrumentation Optional features allow users to implement various selectable operating conditions, including input range, data format select, and output data mode. The AD9461 is available in a Pb-free, 100-lead, surface-mount, plastic package (100-lead TQFP_EP) specified over the industrial temperature range −40°C to +85°C. PRODUCT HIGHLIGHTS GENERAL DESCRIPTION The AD9461 is a 16-bit, monolithic, sampling, analog-to-digital converter (ADC) with an on-chip track-and-hold circuit. It is optimized for performance, small size, and ease of use. The AD9461 operates up to 130 MSPS, providing a superior signalto-noise ratio (SNR) for instrumentation, medical imaging, and radar receivers using baseband (
