SBASAE1A October 2021 – March 2022 AFE4960
PRODUCTION DATA
The AFE4960 can be configured as either a 2-channel ECG receiver or as a 1-channel ECG receiver and a respiration impedance channel. The AFE signal chains can interface in a flexible manner to up to 4 electrodes. A Right Leg Drive (RLD) amplifier output, can be used to set the body bias. The AFE has DC lead biasing for lead on/off detection, and AC lead biasing for measuring the lead impedance. Pacemaker pulse detection is supported on one channel.
All the signal chain outputs are converted by a single ADC in well-defined time slots and stored as 24-bit words in a 128-sample FIFO which can be read out using a SPI or an I2C interface.
The AFE4960 is a fully integrated solution to realize a 3-lead ECG system. Synchronized operation of two AFEs in parallel can be used to realize a 5-lead ECG.
