AD9432BSTZ-105

Analog To Digital Converters (ADC) Overview

The AD9432BSTZ-105 is a 12-bit monolithic sampling analog-to-digital converter (ADC) fabricated on an advanced BiCMOS process. It operates at conversion rates up to 105 MSPS with a 500 MHz full-power analog bandwidth and requires only a single 5.0 V supply. The device integrates an on-chip track-and-hold circuit, input buffer, and voltage reference. Digital outputs are TTL/CMOS-compatible with a separate 3.3 V logic supply pin. It supports differential or single-ended encode inputs and provides twos complement output coding. The component is specified over the industrial temperature range of −40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix BSTZ against the manufacturer's current ordering guide to confirm package type and tape/reel configuration. Ensure the selected variant matches the required thermal characteristics and lead finish specifications for the target PCB assembly process. Confirm availability through authorized distributors as stock levels fluctuate.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution and 105 MSPS sampling rate are required within the industrial temperature range. Consider the integrated reference and track-and-hold features if external driver components are undesirable. Evaluate the 5.0 V analog supply requirement against available system rails and ensure the 3.3 V digital interface aligns with downstream logic families.

Analog To Digital Converters (ADC) Part Context

The AD9432 belongs to Analog Devices' family of high-speed pipeline ADCs designed for broadband applications. It shares architectural similarities with the AD9430 and AD9433 but offers distinct speed and interface configurations. The BSTZ suffix typically denotes a specific packaging option within the 52-lead LQFP or TQFP_EP variants offered for this series.

Analog To Digital Converters (ADC) Replacement Considerations

The AD9433BSVZ-105 is a confirmed substitute offering identical 12-bit resolution and 105 MSPS performance in a compatible 52-lead TQFP_EP package. Verify pinout compatibility and thermal resistance differences before implementation.
