AD9433BSVZ-105

Analog To Digital Converters (ADC) Overview

The AD9433BSVZ-105 is a 12-bit, monolithic sampling analog-to-digital converter (ADC) fabricated on an advanced BiCMOS process. It operates at a maximum conversion rate of 125 MSPS and features an on-chip track-and-hold circuit with a 750 MHz full power analog bandwidth. The device requires a 5.0 V analog supply and a 2.5 V to 3.3 V digital supply. Key specifications include a typical Signal-to-Noise Ratio (SNR) of 68 dB at 105 MSPS, differential nonlinearity (DNL) of ±0.25 LSB, and integral nonlinearity (INL) of ±0.5 LSB. It supports user-selectable offset binary or twos complement data formats.

Analog To Digital Converters (ADC) Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet pinout and package dimensions. Confirm the ordering suffix matches the required sampling rate variant. Ensure compliance with RoHS directives and verify humidity sensitivity handling requirements during storage and assembly.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a 12-bit resolution and up to 125 MSPS sampling rate are required for IF sampling applications. Consider the 5 V analog supply requirement and TTL/CMOS output compatibility. Evaluate the internal reference capability against system noise floor requirements before choosing between external or internal reference configurations.

Analog To Digital Converters (ADC) Part Context

The AD9433 belongs to Analog Devices' high-performance ADC family designed for wideband and high IF carrier systems. It serves as a direct pin-compatible upgrade to the AD9432, offering improved sampling rates while maintaining the same footprint. This continuity facilitates design transitions in existing cellular infrastructure and radar receiver architectures.

Analog To Digital Converters (ADC) Replacement Considerations

The AD9433 is pin-compatible with the AD9432. Verify that the target application can accommodate the higher sampling rate and ensure power supply voltages match the 5 V analog and 3.3 V digital requirements specified for the AD9433.
