1. True 16-bit linearity.
GENERAL DESCRIPTION
2. High performance: outstanding SNR performance for
baseband IFs in data acquisition, instrumentation,
magnetic resonance imaging, and radar receivers.
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.
3. 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.
4. Packaged in a Pb-free, 100-lead TQFP/EP.
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.
5. Clock duty cycle stabilizer (DCS) maintains overall ADC
performance over a wide range of clock pulse widths.
6. Out-of-range (OR) outputs indicate when the signal is
beyond the selected input range.
