LT1112/LT1114 Dual/Quad Low Power Precision, Picoamp Input Op Amps DESCRIPTIO FEATURES S8 Package – Standard Pinout The LT1112 dual and LT1114 quad op amps achieve a new Offset Voltage – Prime Grade: 60µV Max standard in combining low cost and outstanding precision Offset Voltage – Low Cost Grade specifications. (Including Surface Mount Dual/Quad): 75µV Max The performance of the selected prime grades matches or Offset Voltage Drift: 0.5µV/°C Max exceeds competitive devices. In the design of the LT1112/ Input Bias Current: 250pA Max LT1114 however, particular emphasis has been placed on 0.1Hz to 10Hz Noise: 0.3µVP-P, 2.2pAP-P optimizing performance in the low cost plastic and SO Supply Current per Amplifier: 400µA Max packages. For example, the 75µV maximum offset voltage
