AFE4960YBGR

Analog Front End (AFE) Overview

The AFE4960YBGR is a two-channel analog front end designed for clinical wearable ECG applications. It supports configurable operation as dual-channel ECG or single-channel ECG with respiration impedance measurement. The device integrates programmable instrumentation amplifiers, right leg drive (RLD) output, and pace pulse detection on one channel. Electrical specifications include an input noise of 13 µVpp at INA gain of 3 and 5 µVpp at INA gain of 12 within the 0.5-150 Hz band. Power consumption is rated at 222 μA per channel in dual-channel ECG mode. The component operates on supply voltages of 1.7 V to 1.9 V for both Rx and IO domains.

Analog Front End (AFE) Feature Summary

• Configurable as 2-channel ECG or 1-channel ECG plus 1-channel respiration impedance
• Integrated pace pulse detection and continuous lead on/off detection modes
• Supports IEC 60601-2-47:2012/(R)2016 and IEC 60601-2-27:2011(R)2016 compliance
• 128-sample depth FIFO with 24-bit word storage accessible via SPI or I2C

Analog Front End (AFE) Applications

• Wireless patches for in-patient and out-patient monitoring
• Event monitors for arrhythmia detection
• Hand-held ECG monitors
• Portable multi-lead ECG systems
• Patient vital sign monitoring including Holter and stress tests

Analog Front End (AFE) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current package addendum to confirm carrier type and quantity. The YBGR suffix indicates a large tape and reel containing 3000 units. Confirm moisture sensitivity level and peak reflow temperature requirements during assembly planning. Ensure the procurement source provides valid RoHS compliance documentation matching the SNAGCU lead finish specification.

Analog Front End (AFE) Selection Notes

Select this component when designing systems requiring integrated bio-impedance measurement alongside ECG acquisition. The device supports up to four electrodes and can be synchronized in parallel to extend capabilities to five-lead configurations. Verify that the application requires the specific 2.6 mm x 2.6 mm DSBGA footprint. Check interface compatibility for SPI or I2C selection via pin configuration.

Analog Front End (AFE) Part Context

This part belongs to the AFE4960 series from Texas Instruments, specifically tailored for clinical wearables. The YBGR suffix designates the DSBGA (YBG) package variant with 36 pins. It shares architectural similarities with other members of the family but differs in packaging and standard shipping quantities compared to cut-tape variants.

Analog Front End (AFE) Replacement Considerations

Direct functional replacements within the same package are limited. Evaluate the AFE4960YBGT if smaller sample quantities are required, noting the identical electrical characteristics but different carrier format.
