The AFE4410YZR is a low power integrated analog front end (AFE) from Texas Instruments designed for wearable optical heart-rate monitoring and biosensing applications. It provides 24-bit resolution and supports up to 3 time-multiplexed photodiode input channels.
The device includes a transmitter capable of driving up to 4 LEDs in common anode configuration with programmable LED current up to 200 mA. The receiver section features transimpedance gain from 10 kΩ to 2 MΩ and individual DC offset subtraction. Digital ambient subtraction is performed at the ADC output to maintain accuracy.
The AFE4410YZR offers a dynamic range of 100 dB and a FIFO with 128 sample depth for data buffering. It operates over a -20°C to +70°C temperature range and is available in a 30-ball DSBGA (30-DSBGA) package with 0.4 mm pitch for space-constrained wearable designs.
This AFE supports both I2C and SPI interfaces and requires multiple supply voltages: 3 V to 5.25 V for the transmitter, 1.8 V to 1.9 V (LDO bypass) or 2.0 V to 3.6 V (LDO enabled) for the receiver, and 1.7 V to Rx_SUP for I/O. Its low power consumption enables continuous operation in battery-powered wearables.
