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
