Product DetailsThe 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).
- True 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. 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.
- OR (out-of-range) outputs indicate when the signal is beyond the selected input range.
- MRI receivers
- Multi-carrier, multimode cellular receivers
- Antenna array positioning
- Power amplifier linearization
- Broadband wireless
- Radar, infrared imaging
- Communications instrumentation

Evaluation Kits (1)
The high speed ADC FIFO evaluation kit includes the latest version of ADC Analyzer and a buffer memory board to capture blocks of digital data from the Analog Devices, Inc., high speed analog-to-digital converter (ADC) evaluation boards. The FIFO board is connected to the PC through a USB port and is used with ADC Analyzer to quickly evaluate the performance of high speed ADCs. Users can view an FFT for a specific analog input and encode rate to analyze SNR, SINAD, SFDR, and harmonic information.
The evaluation kit is easy to set up. Additional equipment needed includes an Analog Devices high speed ADC evaluation board, a signal source, and a clock source. Once the kit is connected and powered, the evaluation is enabled instantly on the PC.
The HSC-ADC-EVALB-DCZ can be used with single and multichannel ADCs and converters with demultiplexed digital outputs.
