OPA4277UA/2K5E4 Product Details

OPA4277UA/2K5E4 Overview


Packaged in a SOIC case, the buffer op amp is ready to use. An op amp ic of the OPERATIONAL AMPLIFIER type. The op amp is delivered to you in a Tape and Reel case. There is a growing number of terminations approaching the number of 14. The pins on this board total to 14 in total. I would like to remind you that this buffer op amp should be powered by an 15V battery. A total of 14 pins are present on the instrumentation amplifier. There is an input offset voltage of 50μV for this buffer op amp. 140dB should remain the voltage gain. For the buffer op amp to operate properly, it must be above the temperature of -40°C degrees Celsius. No temperature greater than 85°C should be used. The linear amplifier consists of 4 different elements in total. For packing the buffer amplifier, the TR-axis is adopted. In terms of the supply voltage, this electrical part is capable of operating at low voltage levels of under 18V. As a rule of thumb, you should conduct this electronic part under a dual voltage supply of 18V volts.
