OPA121KU Overview


The linear amplifier is packaged in a 8-SOIC (0.154, 3.90mm Width) case which makes it easy for the consumer to handle. The instrumentation amplifier in this picture is of the General Purpose-type. In the case of Tube cases, linear amplifier will be delivered. In recent months, the number of terminations has approached 8. There are a total of 8 pins on this op amp. As a reminder, this buffer op amp should be powered by 15V battery and that the battery should be inserted in the amplifier. A type of Operational Amplifier op amp ic can be identified by the fact that this is a type of Operational Amplifier device. In total, the buffer amplifier consists of 8 pins. With regard to input offset voltage, instrumentation amplifier is rated at 3mV. This electronic component is recommended to be mounted using the mounting type Surface Mount. According to the manufacturer, this buffer op amp works well at 0°C~70°C , which is a good operating temperature. The buffer amplifier is capable of operating from a supply current of 2.5mA . It is recommended to keep the voltage gain at 114dB at all times. There are a total of 1 channels available on the op amps. The operating supply voltage of instrumentation amplifier is rated 18V voltage. Instrumentation amplifiers are numbered by their Difet? series.
