The AD9446 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
product operates up to a 100 MSPS, providing superior SNR for
instrumentation, medical imaging, and radar receivers
employing baseband (<100 MHz) 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 AD9446 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
1.
True 16-bit linearity.
2.
High performance: outstanding SNR performance for
baseband IFs in data acquisition, instrumentation,
magnetic resonance imaging, and radar receivers.
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 package.
5.
Clock duty cycle stabilizer (DCS) maintains overall ADC
performance over a wide range of clock pulse widths.
6.
OR (out-of-range) outputs indicate when the signal is
beyond the selected input range.
