OP249:  Dual, Precision JFET High Speed Operational Amplifier

Product Description

The OP249 is a high speed, precision dual JFET op amp, similar to the popular single op amp, the OP42. The OP249 outperforms available dual amplifiers by providing superior speed with excellent dc performance. Ultrahigh open-loop gain (1 kV/mV minimum), low offset voltage, and superb gain linearity makes the OP249 the industry’s first true precision, dual high speed amplifier.

With a slew rate of 22 V/μs typical and a fast settling time of less than 1.2 μs maximum to 0.01%, the OP249 is an ideal choice for high speed bipolar DAC and ADC applications. The excellent dc performance of the OP249 allows the full accuracy of high resolution CMOS DACs to be realized.

Symmetrical slew rate, even when driving large load, such as, 600 Ω or 200 pF of capacitance and ultralow distortion, make the OP249 ideal for professional audio applications, active filters, high speed integrators, servo systems, and buffer amplifiers.

The OP249 provides significant performance upgrades to the TL072, AD712, OP215, MC34082, and LT1057.

Applications

  • Output amplifier for fast DACs
  • Signal processing
  • Instrumentation amplifiers
  • Fast sample-and-holds
  • Active filters
  • Low distortion audio amplifiers
  • Input buffer for ADCs
  • Servo controllers
  • Data Sheet, Rev. F, 5/07

    Features

    • Fast slew rate: 22 V/μs typical
    • Settling time (0.01%): 1.2 μs maximum
    • Offset voltage: 300 μV maximum
    • High open-loop gain: 1000 V/mV minimum
    • Low total harmonic distortion: 0.002% typical
    • Improved replacement for AD712, LT1057, OP215, TL072, and MC34082
