AD9446BSVZ-80

Analog To Digital Converters (ADC) Overview

The AD9446BSVZ-80 is a 16-bit, monolithic sampling analog-to-digital converter (ADC) with an on-chip track-and-hold circuit. It operates at a guaranteed maximum sampling rate of 80 MSPS and requires 3.3 V and 5.0 V power supplies. The device features buffered analog inputs supporting a differential full-scale input range of 2.0 V p-p to 4.0 V p-p. Digital outputs are available in LVDS or CMOS formats, with selectable data formats including offset binary or twos complement. It includes an internal reference and clock duty cycle stabilizer.

Analog To Digital Converters (ADC) Feature Summary

• Integrated clock duty cycle stabilizer maintains performance across varying clock pulse widths.
• On-chip track-and-hold circuit with adjustable analog input range simplifies system design.
• Selectable digital output modes support both LVDS and CMOS interfaces for flexible data capture.

Analog To Digital Converters (ADC) Applications

• MRI receivers
• Radar systems
• Medical imaging instrumentation

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix designation against the manufacturer's current ordering guide to confirm the 80 MSPS speed grade and package variant. Ensure that the procurement documentation matches the exact part number requirements for your design specifications.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution and 80 MSPS sampling rate are required for baseband applications. Consider the 100-lead TQFP/EP package constraints and thermal management needs due to the exposed heat sink requirement for proper operation within the specified temperature range.

Analog To Digital Converters (ADC) Part Context

This component belongs to the AD9446 family of high-speed ADCs from Analog Devices. It shares architectural similarities with the AD9446-100 variant but is specifically rated for an 80 MSPS maximum conversion rate. Both variants utilize the same 100-lead plastic surface-mount package.

Analog To Digital Converters (ADC) Replacement Considerations

The AD9446BSVZ-100 serves as a higher-speed alternative within the same family. Verify compatibility regarding pinout and software configuration if substituting between the 80 MSPS and 100 MSPS versions.
