AFE5832LPZAV

Analog Front End (AFE) Overview

The AFE5832LPZAV is a 32-channel ultrasound analog front end (AFE) designed for portable systems. It integrates low-noise amplifiers, programmable attenuators, and ADCs in a 15 mm × 15 mm NFBGA-289 package. The device operates at 12-bit resolution with 40 MSPS or 10-bit resolution with 50 MSPS sampling rates. Power consumption is rated at 18.5 mW per channel. It features a passive continuous wave mixer and supports LVDS output interfaces for FPGA connectivity.

Analog Front End (AFE) Feature Summary

• 32-channel architecture with integrated LNA, programmable attenuator, and LPF
• Dual-resolution ADC: 12-bit at 40 MSPS or 10-bit at 50 MSPS
• Low power consumption of 18.5 mW per channel
• Passive CW mixer with 16-phase delay options for beamforming

Analog Front End (AFE) Applications

• Portable medical ultrasound imaging systems
• Handheld diagnostic ultrasound devices
• Battery-powered ultrasound scanners

Analog Front End (AFE) Procurement Notes

Verify the specific suffix ZAV against the official Texas Instruments datasheet to confirm pinout and electrical characteristics. Ensure compatibility with the required NFBGA-289 footprint during PCB design. Confirm moisture sensitivity levels and reflow soldering profiles prior to assembly.

Analog Front End (AFE) Selection Notes

Select this component when a high channel count is required within a small form factor. It is suitable for applications prioritizing low power consumption over maximum throughput. Compare against the standard AFE5832 if higher sampling rates are needed, as this LP variant optimizes for portability.

Analog Front End (AFE) Part Context

This part belongs to the AFE5832LP series, which utilizes a multi-chip module (MCM) construction combining VCA and ADC dies. It is distinct from the AFE58JD32 series, which offers different channel counts and interface options. The LP designation indicates the low-power optimized version for portable use cases.

Analog Front End (AFE) Replacement Considerations

Direct substitutes include other parts within the AFE5832 family, such as the AFE5832LPZAR. Verify that any replacement maintains the same NFBGA-289 package dimensions and pin configuration.
