OPA344UA Product Details

OPA344UA Overview


It is packaged in an 8-SOIC (0.154, 3.90mm Width)-case that protects the operational amplifiers from damage. An op amp of this type is a General Purpose-type. As far as the packaging is concerned, buffer op amp is delivered in a Tube case. It is estimated that there will be at least 8 terminations this year. A total of 8 pins are attached to buffer op amp. As a reminder, this buffer op amp should be powered by 5.5V 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. Op amp ic rates 1mV for input offset voltage. This electronic part is recommended for mounting type Surface Mount. In terms of operating temperature, this instrumentation amplifier is well suited to a temperature range of -40°C~85°C. A supply current of 150μA can be used to operate this linear amplifier. There should be no change in the voltage gain at 122dB. There are a total of 1 channels available on the op amps. One of its many advantages is that buffer op amp outputs Rail-to-Rail signals. Buffer op amp series numbers are indicated by the MicroAmplifier™.
