LT1014A 四路精密运算放大器
The LT1014, LT1014A, and LT1014D are quad precision operational amplifiers with 14-pin industry-standard configuration. They feature low offset-voltage temperature coefficient, high gain, low supply current, and low noise.
The LT1014, LT1014A, and LT1014D can be operated with both dual ±15-V and single 5-V power supplies. The common-mode input voltage range includes ground, and the output voltage can also swing to within a few milivolts of ground. Crossover distortion is eliminated.
The LT1014C and LT1014D are characterized for operation from 0°C to 70°C. The LT1014I and LT1014DI are characterized for operation from –40°C to 105°C. The LT1014M, LT1014AM and LT1014DM are characterized for operation over the full military temperature range of –55°C to 125°C
