LM346DT Product Details

LM346DT Overview


There is a SO case package that contains the instrumentation amplifiers. The instrumentation amplifier in this picture is of the OPERATIONAL AMPLIFIER-type. Upon delivery, op amp ic is packaged in a Tape & Reel case. We are approaching the 16h termination of the year. In total, there are 16 pins on this op amp ic. This linear amplifier should be powered by an 15V battery. There are two types of Operational Amplifier op amps in this case, and this device falls into one of them. It is recommended to keep the voltage gain at 120dB at all times. For this linear amplifier to work, the temperature should not be below 0°C. In order to avoid damage to the product, operational amplifiers should only be used at temperatures below 70°C. In order for this electronic part to be conducted successfully, you should use a dual supply voltage of 22V.
