In conventional white LED design, the Max1916 low-dropout bias supply for white LEDs is a high performance alternative to the simple ballast resistors. A single resistor is used by this device to set the bias current for three LEDs, which are matched to 0.3%. On enable condition, the MAX1916 consumes only 40uA of supply current and 0.05uA when disabled. The […]

AD8221 is an excellent candidate for bridge measurement because it has low offset and high CMRR over frequency. The bridge can be directly connected to the inputs of the amplifier as shown in figure below. The AD8221 is a gain programmable, in its class, high performance instrumentation amplifier that delivers the industry’s highest CMRR over frequency. Today, the CMRR of […]

While traveling, charging of the mobile phone, cellphone battery is a big problem as power supply source is not generally accessible. Battery will go flat within five to six hours if you keep your cellphone switched on continuously, making the cellphone useless. When your distance from the nearest relay station increases, a fully charged battery becomes necessary. Below is simple […]
