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
- 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.
APPLICATIONS
- MRI receivers
- Multi-carrier, multimode cellular receivers
- Antenna array positioning
- Power amplifier linearization
- Broadband wireless
- Radar, infrared imaging
- Communications instrumentation
