OPA228U/2K5 Product Details

OPA228U/2K5 Overview


A 8-SOIC (0.154, 3.90mm Width) case is used to package the op amp. General Purpose-type instrumentation amplifiers are used in this application. The case in which buffer amplifier is delivered is called a Tape & Reel (TR) case. It is estimated that there will be 8 terminations in the next few months. There are a total of 8 pins on this op amp. It should be noted that this op amp is a type of Operational Amplifier device. There are 8 pins on this chip. 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~85°C . On this instrumentation amplifier, there are 1 circuits that are connected together. The instrumentation amplifier is packed in the form of TAPE AND REEL. As a recommendation, this electronic component should be used with a power supply that can deliver 3.7mA.
