The PA164/PA165 are high density power amplifier ICs that elevate the performance benchmarks and thermal management efficiency for single-chip power amplifiers. These devices are capable of providing 1A/4A of output current continuously, and up to 10A PEAK output for the PA165, while operating on voltage supplies of up to 200V.

These ICs are designed to use separate supplies for the amplifier core and the output stage to help optimize overall power dissipation capabilities of up to 28W of internally generated heat.

Mouser Supplies ROHM Semiconductor BH1790GLC Optical Heart Rate Sensor. ROHM Semiconductor BH1790GLC Optical Heart Rate Sensor is a photodiode designed to measure pulse waves, which are changes in the volume of a blood vessel that occur when the heart pumps blood. Pulse waves are detected by measuring the change in volume using an optical sensor and green LED. The BH1790GLC Optical Sensor features an optical filter optimized for pulse wave detection. This filter minimizes the effects of ambient light and increases the sensitivity and accuracy of the sensor block. The BH1790GLC Optical Heart Rate Sensor is offered in a compact WLGA010V28 package. The Sensor's small 2.8mm x 2.8mm footprint and low power requirements make it ideal for wearable devices such as sports bands and smart watches.
