1pA 70 dB Instrumentational OP Amps 0.00001μA 6V 3.5V~12V ±1.75V~6V OPA2743 8 Pins 8-SOIC (0.154, 3.90mm Width)
OPA2743UA/2K5 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 Tape & Reel (TR) 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 5V battery and that the battery should be inserted in the amplifier. In total, the buffer amplifier consists of 8 pins. Op amp ic rates 7mV 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. There should be no change in the voltage gain at 120dB. One of its many advantages is that buffer op amp outputs Rail-to-Rail signals. There are 2 elements in this buffer amplifier. The operating supply voltage of the buffer op amp is rated at 6V. An buffer amplifier is packed in a TR-shape according to the design. For optimal performance, this electrical part should be connected to a supply with a current of 1.1mA.
