OPA1644AIDR Overview
In order to protect the op amps, a 14-SOIC (0.154, 3.90mm Width) case is used. An op amp of this type is a Audio-type. A Tape & Reel (TR) case is used for delivering the op amp. A total of 14 terminations have been reported in the past few weeks. In this case, there are 14 pins on the board. As a reminder, this buffer op amp should be powered by 18V battery and that the battery should be inserted in the amplifier. It should be noted that this op amp is a type of Operational Amplifier device. The buffer op amp includes 14 pins. Op amp ic rates 3.5mV for input offset voltage. Surface Mount is the recommended mounting type for this linear amplifier. It is important to note that this linear amplifier works well at a temperature of -40°C~85°C when it comes to operating temperatureOperational amplifier can operate supply current at 1.8mA. Voltage gain should remain at 134dB. There are more than a few advantages to using this instrumentation amplifier, one of which is that it outputs Rail-to-Rail signals. The buffer op amp is rated for an operating voltage of 4 when it comes to the power supply. To pack the operational amplifier ics, TR is adopted as the packing method. In this case, SoundPlus? represents the instrumentation amplifiers' series number.
