Description
AI
The AD9460 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 AD9460 operates up to 105 MSPS, providing a superior signal-to-noise ratio (SNR) for instrumentation, medical imaging, and radar receivers using baseband (<100 MHz) and IF frequencies.The ADC requires 3.3 V and 5.0 V power supplies and a low voltage differential input clock for full performance operation. No external reference or driver components are required for many applications. Data outputs are CMOS or LVDS compatible (ANSI-644 compatible) and include the means to reduce the overall current needed for short trace distances.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.PRODUCTS HIGHLIGHTSTrue 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. Out-of-range (OR) outputs indicate when the signal is beyond the selected input range.APPLICATIONSMRI receiversMulticarrier, multimode, cellular receiversAntenna array positioningPower amplifier linearizationBroadband wirelessRadarInfrared imagingCommunications instrumentation
