AFE58JD28ZAV

Analog Front End (AFE) Overview

The AFE58JD28ZAV is a 16-channel ultrasound analog front end (AFE) designed for high-performance medical imaging systems. It integrates two 14-bit, 65-MSPS or two 12-bit, 80-MSPS ADCs per channel, alongside digital demodulators and passive continuous wave (CW) mixers. The device supports both JESD204B and LVDS interfaces for data transmission. Key electrical specifications include an input voltage range of 3.15 V to 3.6 V and an active supply current of approximately 260 mA. It operates within a commercial temperature range of 0°C to +85°C and utilizes a 289-pin NFBGA package.

Analog Front End (AFE) Feature Summary

• 16-channel architecture with integrated 14-bit/65-MSPS or 12-bit/80-MSPS ADCs
• Supports JESD204B and LVDS digital output interfaces
• Includes digital demodulator and passive CW mixer functionality
• Low noise performance with 0.8-nV/√Hz input noise density

Analog Front End (AFE) Applications

• Medical ultrasound imaging systems
• Portable ultrasound devices requiring low power consumption
• High-channel-count ultrasound transducer arrays

Analog Front End (AFE) Part Context

The AFE58JD28ZAV belongs to the Texas Instruments AFE58 family of ultrasound analog front ends. This series is engineered to reduce system complexity by integrating multiple signal chain components into a single solution. The ZAV suffix typically denotes specific packaging and environmental ratings consistent with TI's catalog product line for this component type.

Analog Front End (AFE) Replacement Considerations

Direct pin-to-pin replacements within the same family include the AFE58JD28 and variants such as AFE58JD28ZAV.A or AFE58JD28ZAV.B. These parts share identical functional descriptions and interface capabilities. Designers should verify that any substitute maintains compatibility with the existing PCB footprint and thermal management requirements.
