MAX86140/ MAX86141 Best-in-Class Optical Pulse Oximeter and Heart-Rate Sensor for Wearable Health General Description The MAX86140/MAX86141 are ultra-low-power, completely integrated, optical data acquisition systems.
On the transmitter side, the MAX86140/MAX86141 have three programmable high-current LED drivers that can be configured to drive up to six LEDs using an external 3x2:1 mux.
With two MAX86140/MAX86141 devices working in master-slave mode, the LED drivers can drive up to twelve LEDs using an external 3x2:1 mux.
On the receiver side, MAX86140 consists of a single optical readout channel, while the MAX86141 has two optical readout channels that can operate simultaneously.
The devices have lownoise signal conditioning analog front-end (AFE) including 19-bit ADC, an industry-lead ambient light cancellation (ALC) circuit, and a picket fence detect and replace function.
Due to the low power consumption, compact size, ease of use, and industry-lead ambient light rejection capability of MAX86140/MAX86141, the devices are ideal for a wide variety of optical-sensing applications, such as pulse oximetry and heart rate detection.
The MAX86140/MAX86141 operate on a 1.
8V main supply voltage and a 3.
1V to 5.
5V LED driver supply voltage.
Both devices support a standard SPI compatible interface and fully autonomous operation.
Each device has a large 128-word built-in FIFO.
The MAX86140/MAX86141 is available in compact wafer-level package (WLP) (2.
048 x 1.
848mm) with 0.
4mm ball pitch.
