AFE5801IRGCT

Analog Front End (AFE) Overview

The AFE5801IRGCT is an analog front-end integrated circuit manufactured by Texas Instruments, designed for ultrasound imaging applications. It integrates eight channels of variable gain amplifiers (VGAs) and analog-to-digital converters (ADCs). The device features a 12-bit resolution with a sampling rate of 65 MS/s per channel. It operates on dual power supplies: analog voltage ranges from 3 V to 3.6 V, and digital voltage ranges from 1.7 V to 1.9 V. The component utilizes a serial 5-wire interface for configuration and data output. It is housed in a 64-pin VQFN package suitable for surface-mount technology and supports an operating temperature range from -40°C to +85°C.

Analog Front End (AFE) Feature Summary

• Integrates 8-channel VGA and ADC array with 12-bit resolution
• Supports high-speed data acquisition at 65 MS/s per channel
• Includes internal and external reference options for flexible biasing
• Provides differential input and LVDS output interfaces

Analog Front End (AFE) Applications

• Ultrasound imaging systems
• Medical diagnostic equipment requiring multi-channel signal acquisition
• High-performance data acquisition systems

Analog Front End (AFE) Procurement Notes

Verify the specific suffix 'T' indicates cut-tape packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets. Ensure compatibility with the required 5-wire serial interface protocol during system integration planning.

Analog Front End (AFE) Selection Notes

Select this component for designs requiring eight simultaneous ultrasound channels with integrated amplification and digitization. Compare against the AFE5851 if sixteen channels are needed. Ensure the PCB layout supports the VQFN-64 thermal pad requirements and provides adequate decoupling for the 1.8 V analog and digital supply rails.

Analog Front End (AFE) Part Context

This part belongs to the AFE5801 family of ultrasound analog front-ends. It is functionally similar to the AFE5801IRGCR, differing primarily in packaging quantity rather than electrical characteristics. The IRGCT designation specifically denotes the tape-and-reel cut-tape variant of the standard reel product.

Analog Front End (AFE) Replacement Considerations

The AFE5801IRGCR is a direct functional substitute with identical electrical specifications, differing only in shipping packaging format.
