OPA4234U/2K5G4 Product Details

OPA4234U/2K5G4 Overview


Op amp is packaged in D case. Op amps are OPERATIONAL AMPLIFIER types of amplifier on the chip. Instrumentation amplifier is delivered in a Tape and Reel case. The number of terminations approaches 14. Linear amplifier has a total of 14 pins. Please take in mind that op amp should be run at 15V. Linear amplifier includes 14 pins. Regarding input offset voltage, buffer amplifier rates 250μV voltage. The voltage gain should stay at 120dB. It should not lower than -40°C to operate buffer amplifier. It is recommended that op amp be used at temperatures below 125°C. Op amp has total of 4 elements. The operating supply voltage of instrumentation amplifier is rated 18V voltage. With regard tp supply voltage, op amp is used under 36V. To keep the buffer amps' supply voltage higher than 2.7V. Conduct linear amplifier under the dual suuply voltage of 18V.
