ADA4891-4ARZ-R7 Overview


It is packaged in an 14-SOIC (0.154, 3.90mm Width)-case that protects the operational amplifiers from damage. The instrumentation amplifier in this picture is of the General Purpose-type. The case in which buffer amplifier is delivered is called a Tape & Reel (TR) case. It is estimated that there will be 14 terminations in the next few months. In this case, there are 14 pins on the board. This linear amplifier should be powered by an 3V battery. There are two types of Operational Amplifier op amps in this case, and this device falls into one of them. In total, the buffer amplifier consists of 14 pins. With regards to the offset voltage of the input, buffer amplifier is rated at 10mV. For this electronic part, it is recommended that you mount it with type Surface Mount. In terms of operating temperatures, this buffer amplifier works very well at a temperature of around -40°C~125°C . Operational amplifier can operate supply current at 17.6mA. There should be no change in the voltage gain. As far as the device is concerned, buffer amplifier has 4 channels. On the output type, there are Rail-to-Rail different types of op amps. The operating supply voltage of instrumentation amplifier is rated 5V voltage. For the packing of the instrumentation amplifier, TAPE AND REEL is adopted. There is an 4.4mA quiescent current running through op amp ic.
