DESCRIPTION

· The OB1203 and OB1203LC Sensor Modules by Renesas integrate optical biosensors with proximity and ambient light sensing, ideal for handheld devices.

· The OB1203 PPG biosensor combines light sources, drivers, ADC, and I2C in one package, enabling HR, SpO2, RR, and HRV measurements.

· OB1203LC features photodiodes for visible and near-infrared light, while OB1203SD includes RGB color filters with Lux sensitivity.

· The OB1203’s far-red LED (690nm) reduces sensitivity to skin tone differences and supports SpO2 measurements behind dark IR ink.

FEATURES

· SpO2 measurement less affected by skin color.

· Compact optical biosensor module with integrated LEDs, drivers, and photodetectors.

· PPG output resolution: 16 to 18 bits, with data stored in an 18-bit, 32-sample FIFO memory.

· Programmable measurement rate up to 3200 samples per second.

· Light and color sensor (OB1203SD) with 13 to 20-bit resolution, stable spectral response, and accurate CCT and CIE 1931 XYZ color measurement.

· Proximity sensor with programmable LED up to 250mA, high resolution, and ambient light suppression.

· Industry’s smallest package (4.2 × 2 × 1.2 mm3), wide temperature range (-40°C to +85°C), and low power consumption.

· I2C interface supporting Standard Mode (100kHz) or Fast Mode (400kHz) communication.

APPLICATIONS

· Handheld electronic devices requiring heart rate, oxygen saturation, and stress level monitoring.

· Devices needing accurate ambient light and color sensing.

· Proximity detection in consumer electronics with aesthetic designs.

· Wearable health and fitness devices for continuous health monitoring.

· Industrial designs requiring reliable sensor performance in varying light conditions.
