PRODUCT HIGHLIGHTS

Communications instrumentation

1. True 16-bit linearity.

2. High performance: outstanding SNR performance for

baseband IFs in data acquisition, instrumentation,

magnetic resonance imaging, and radar receivers.

GENERAL DESCRIPTION

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.

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.

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. OR (out-of-range) outputs indicate when the signal is

beyond the selected input range.
