To drive this ADC in DC-coupled applications, we suggest ADA4938-1. To drive this ADC in AC-coupled applications, we suggest AD8352 or AD8375.

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 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 LVDS-compatible (ANSI-644) or CMOS-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 data format select and output data mode.

The AD9446 is available in a 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. An output clock simplifies data capture.
4. Packaged in a Pb-free, 100-lead TQFP/EP.
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.

The model number is a specific version of a generic that can be purchased or sampled.

Status indicates the current lifecycle of the product. This can be one of 4 stages:

• Pre-Release: The model has not been released to general production, but samples may be available.
• Production: The model is currently being produced, and generally available for purchase and sampling.
• Last Time Buy: The model has been scheduled for obsolescence, but may still be purchased for a limited time.
• Obsolete: The specific part is obsolete and no longer available. Other models listed in the table may still be available (if they have a status that is not obsolete).

The package for this IC (i.e. DIP, SOIC, BGA). An Evaluation Board is a board engineered to show the performance of the model, the part is included on the board.
