OPA338UA Product Details

OPA338UA Overview


Packaged in a 8-SOIC (0.154, 3.90mm Width) case, the buffer op amp is ready to use. An op amp ic of the General Purpose type. The op amp is delivered to you in a Tube case. There is a growing number of terminations approaching the number of 8. The pins on this board total to 8 in total. I would like to remind you that this buffer op amp should be powered by an 5V battery. I would like to specify that this buffer amplifier belongs to the Operational Amplifier-type of devices. A total of 8 pins are present on the instrumentation amplifier. There is an input offset voltage of 500μV for this buffer op amp. The mounting type that is recommended for this electrical part is Surface Mount. In relation to the operating temperature of this buffer op amp, it works well at an average of -40°C~85°C . As long as the supply current of the chip does not exceed 525μA, this op amp ic can operate. Keeping the voltage gain at 120dB is the best course of action. During the manufacturing process, this buffer amplifier is divided into 1 circuits. One of the many advantages that this linear amplifier has, among many other things, is the fact that it outputs Rail-to-Rail signals. As the name implies, MicroAmplifier™ refers to the series of the buffer op amp.
