INA146UA/2K5E4 Product Details

INA146UA/2K5E4 Overview


There is a D case package that contains the instrumentation amplifiers. The instrumentation amplifier in this picture is of the INSTRUMENTATION AMPLIFIER-type. Upon delivery, op amp ic is packaged in a Tape and Reel case. We are approaching the 8h termination of the year. In total, there are 8 pins on this op amp ic. This linear amplifier should be powered by an 15V battery. There are two types of Instrumentation Amplifier op amps in this case, and this device falls into one of them. 8 pins are located on the operational amplifiers. The input offset voltage is 5mV. It is recommended to keep the voltage gain at 40dB at all times. On the buffer amps, there are 1 channels that can be used. For this linear amplifier to work, the temperature should not be below -40°C. In order to avoid damage to the product, operational amplifiers should only be used at temperatures below 85°C. The total number of elements in this buffer amplifier is 2. Under 36V is the minimum supply voltage for this electric component. Over 2.7V is a recommended supply voltage for buffer ampsIn order for this electronic part to be conducted successfully, you should use a dual supply voltage of 18V. 600μA quiescent currents are flowing through buffer op amp. In order for the op amp resistance to remain within the 110kOhm range, the op amp should be tested.
