AFE5808AZCF

Analog Front End (AFE) Overview

The AFE5808AZCF is a fully integrated 8-channel ultrasound analog front-end (AFE) manufactured by Texas Instruments. It operates within a supply voltage range of 1.7 V to 1.9 V and supports sampling rates up to 65 MS/s. The device offers selectable resolutions of 12-bit or 14-bit, achieving a signal-to-noise ratio (SNR) of 77 dBFS with a gain error of +/-0.5 dB. Designed for surface-mount installation, it is housed in an nFBGA-135 package. The component functions within a temperature range of 0°C to +85°C and dissipates approximately 190 mW of power.

Analog Front End (AFE) Applications

• Ultrasound imaging systems
• Medical diagnostic equipment
• Analog front-end signal processing

Analog Front End (AFE) Procurement Notes

Verify the specific suffix 'ZCF' against the official datasheet to confirm package type and moisture sensitivity level. Confirm RoHS compliance status through the manufacturer's documentation. Ensure the development kit AFE5808AEVM is available for validation purposes. Check current production lifecycle status as availability may vary.

Analog Front End (AFE) Selection Notes

Select this component when an 8-channel ultrasound solution with integrated ADC and VGA is required. Compare against the AFE5801 for similar channel counts but different packaging. Consider the AFE58JD48 for higher channel counts (16) and faster sampling speeds (125 MS/s). Verify that the 1.7V–1.9V supply requirement aligns with the system design.

Analog Front End (AFE) Part Context

The AFE5808AZCF belongs to the AFE5808A series of analog front-ends. It is distinct from the AFE5809EVM, which is an evaluation board for the AFE5809. The part is categorized under Data Converter ICs and Analog Front Ends. It is designed to simplify ultrasound transducer interface designs by integrating multiple stages into a single chip.
