BU7421SG-TR Product Details

BU7421SG-TR Overview


In order to protect the op amps, a SC-74A, SOT-753 case is used. There are two types of operational amplifiers in this circuit. In the case of Tape & Reel (TR) cases, linear amplifier will be delivered. In recent months, the number of terminations has approached 5. It consists of a total of 5 pins in total. It would be helpful if you could remember that this op amp ic should be powered by an 3V battery. A type of Operational Amplifier buffer op amp is what this device is specifically, to be more precise. It has 5 pins that make up the linear amplifier. In terms of input offset voltage, operational amplifier rates 1mV. This electronic component is recommended to be mounted using the mounting type Surface Mount. It is recommended that this op amp ic be operated at a temperature no higher than -40°C~105°C for optimal performance. In order for this instrumentation amplifier to operate, the supply current needs to be between 8.5μA and 10 . In total, there are 1 circuits on this buffer amplifier. As a result of this, the buffer amplifier is packed in TAPE AND REEL.
