OPA251UAG4 Product Details

OPA251UAG4 Overview


Op amp is packaged in SOIC case. Op amps are OPERATIONAL AMPLIFIER types of amplifier on the chip. The number of terminations approaches 8. Linear amplifier has a total of 8 pins. Please take in mind that op amp should be run at 15V. Instrumentation amplifier is a part of Operational Amplifier. Linear amplifier includes 8 pins. Regarding input offset voltage, buffer amplifier rates 100μV voltage. Operational amplifier can operate supply current at 27μA. 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 85°C. Op amp has total of 1 elements. The operating supply voltage of instrumentation amplifier is rated 18V voltage. It is used TUBE to pack the op amps. 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.
