ADA4891-3ARZ-RL Overview


It is packaged in an 14-SOIC (0.154, 3.90mm Width)-case that protects the operational amplifiers from damage. A General Purpose-type buffer amplifier is shown here. The case in which buffer amplifier is delivered is called a Tape & Reel (TR) case. In recent months, the number of terminations has approached 14. The pins on this board total to 14 in total. This linear amplifier should be powered by an 3V battery. I would like to specify that this buffer amplifier belongs to the Operational Amplifier-type of devices. There are 14 pins on this chip. Op amp ic rates 10mV for input offset voltage. It is recommended that this electronic component be mounted using the Surface Mount mounting type. In terms of operating temperature, this instrumentation amplifier performs well at a temperature of about -40°C~125°C . You can run this op amp ic on 13.2mA . You should keep the voltage gain at 83dB for the time being. Buffer op amp is equipped with 3 channels on the device. One of the many benefits of this op amp ic is that it emits Rail-to-Rail signals. The operating supply voltage of the buffer op amp is rated at 5V. An buffer amplifier is packed in a TAPE AND REEL-shape according to the design. There is a quiescent current of 4.4mA in this operational amplifier circuit.
