AD9432BSVZ-80

Analog To Digital Converters (ADC) Overview

The AD9432BSVZ-80 is a 12-bit monolithic sampling analog-to-digital converter (ADC) from Analog Devices, operating at a maximum conversion rate of 105 MSPS. It features an on-chip track-and-hold circuit and input buffer, requiring only a single 5.0 V analog supply and a 3.3 V digital supply. The device provides a 2.0 V p-p differential analog input range and outputs data in two's complement format via TTL/CMOS-compatible pins. Key dynamic performance metrics include a Signal-to-Noise Ratio (SNR) of 67 dB and Spurious-Free Dynamic Range (SFDR) of 80 dB at 105 MSPS with a 49 MHz input. Power dissipation is typically 850 mW.

Analog To Digital Converters (ADC) Feature Summary

• Integrates an on-chip voltage reference and track-and-hold circuit to minimize external component requirements.
• Features a dedicated on-chip input buffer for direct driving of differential analog signals.
• Supports both differential and single-ended encode clock inputs with TTL/CMOS compatibility.
• Provides an out-of-range output pin to indicate when digital data reaches positive or negative full scale.

Analog To Digital Converters (ADC) Applications

• Base stations and zero-IF communication subsystems
• Wireless local loop (WLL) systems
• Local multipoint distribution service (LMDS)
• HDTV broadcast cameras and film scanners

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'SVZ' corresponds to the TQFP_EP package variant as defined in the manufacturer's ordering guide. Confirm that the '80' designation aligns with the specified 80 MSPS/105 MSPS operational range. Ensure compliance with industrial temperature specifications ranging from -40°C to +85°C for the intended application environment.
