ADS5433IPJY

Analog To Digital Converters (ADC) Overview

The ADS5433IPJY is a 14-bit, 80 MSPS analog-to-digital converter (ADC) manufactured by Texas Instruments. It operates from a 5 V analog supply and a 3.3 V digital supply, providing 3.3 V CMOS-compatible parallel outputs. The device features an internal reference generator and a differential input range of 2.2 Vpp. Key performance metrics include a typical Signal-to-Noise Ratio (SNR) of 74.4 dBc at 80 MSPS with a 30 MHz input frequency, and a Spurious-Free Dynamic Range (SFDR) of 96.5 dBc under the same conditions. It is housed in a 52-pin HTQFP package with an exposed heatsink.

Analog To Digital Converters (ADC) Applications

• Single and multichannel digital receivers
• Base station infrastructure
• Instrumentation systems
• Video and imaging applications

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix 'PJY' corresponds to the tray packaging configuration as indicated in the datasheet. Confirm that the component meets the industrial temperature range requirements (-40°C to 85°C). Ensure that the power supply voltages align with the specified 5 V for AVDD and 3.3 V for DRVDD during integration.

Analog To Digital Converters (ADC) Selection Notes

Select this component when high spurious-free dynamic range is critical for input frequencies up to 100 MHz. The internal reference simplifies design by removing external components. Consider the 52-pin HTQFP package thermal characteristics if operating near the upper temperature limit or with significant airflow constraints.

Analog To Digital Converters (ADC) Part Context

The ADS5433 is pin-compatible with the ADS5423, ADS5424, AD6644, and AD6645. It utilizes Texas Instruments' BiCom3 complementary bipolar process. The device is designed to offer enhanced SFDR compared to its predecessors while maintaining compatibility with existing system architectures.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS5433I, ADS5423, ADS5424, AD6644, and AD6645 are documented as pin-compatible alternatives. Verify specific performance differences such as SNR and SFDR specifications before substituting.
