Product Overview

LT1112 dual low power precision, picoamp input op amp achieves a new standard in combining low cost and outstanding precision specifications. The performance of the selected prime grades matches or exceeds competitive devices. In the design of the LT1112 however, particular emphasis has been placed on optimizing performance in the low cost packages. The device also provide a full set of matching specifications, facilitating their use in such matching dependent applications as two and three op amp instrumentation amplifiers. Another set of specifications is furnished at ±1V supplies. This, combined with the low 320µA supply current per amplifier, allows the LT1112 to be powered by two nearly discharged AA cells. Applications include picoampere/microvolt instrumentation, two and three op amp instrumentation amplifiers, thermocouple and bridge amplifiers, low frequency active filters, photo current amplifiers, battery-powered systems.
  • Input offset voltage of 75µV maximum (VS = ±1.0V, VS = ±15V, VCM = 0V, TA = 25°C)
  • Input offset current of 230pA (VS = ±15V, VCM = 0V, TA = 25°C)
  • Input bias current of ±280pA maximum (VS = ±15V, VCM = 0V, TA = 25°C)
  • Input noise voltage of 0.9µVP-P max (0.1Hz to 10Hz, VS = ±15V, VCM = 0V, TA = 25°C)
  • Slew rate of 0.30V/µs typical (VS = ±15V, VCM = 0V, TA = 25°C)
  • Gain-bandwidth product of 750 kHz typical (fO = 10KHz, VS = ±15V, VCM = 0V, TA = 25°C)
  • Common mode rejection ratio of 136dB typical (VCM = ±13.5V, VS = ±15V, VCM = 0V, TA = 25°C)
  • Power supply rejection ratio of 126dB typical (VS = ±1.0V to ±20V, VS = ±15V, VCM = 0V, TA = 25°C)
  • Large-signal voltage gain of 5000V/mV typical (VO=±12V, RL = 10Kohm, VS = ±15V, VCM = 0V, TA = 25°C)
  • 8-lead PDIP package, -40°C to 85°C temperature range
