PULSEMON provides low-noise amplification chains and integrates high resolution analog to digital converters (ADC) as well as LED drivers and an acquisition sequencer. It operates with ultra-low power at both the circuit and system level.

Integrated Pulse Oxymeter and Heart Rate Monitor

Chip, architecture & implementation

Photo-plethysmography and applications

KEY FEATURES

• Integrated LED drivers with programmable current from 2 mA to 140 mA (up to 3 LEDs)

• Programmable amplification gain and cutoff frequency

• Multi-channel (multi-sensor) measurement (3 channels in parallel)

• Separate fully programmable sample rate for each ADC and each LED

• Low-power heart rate mode (<0.8 mW including LED current )

• Ultra-fast <1 second data output capability from shutdown mode

• High-resolution receive channel with >14.5 noise-free bits

• Active ambient light removal

APPLICATIONS

• Sport measurement devices (chest free watches)

• Wellness applications (long term measurements on body)

• Medical or paramedical vital sign monitoring applications
