Philips Semiconductors Linear Products Product specification NE/SE531High slew rate operational amplifier 70August 31, 1994 853-0809 13721

DESCRIPTION

The 531 is a fast slewing high performance operational amplifier which retains DC performance equal to the best general purpose types while providing far superior large-signal AC performance. A unique input stage design allows the amplifier to have a large-signal response nearly identical to its small-signal response. The amplifier is compensated for truly negligible overshoot with a single capacitor. In applications where fast settling and superior large-signal bandwidths are required, the amplifier out-performs conventional designs which have much better small-signal response. Also, because the small-signal response is not extended, no special precautions need be taken with circuit board layout to achieve stability. The high gain, simple compensation, and excellent stability of this amplifier allow its use in a wide variety of instrumentation applications.

FEATURES

  • 35V/µs slew rate at unity gain
  • Pin-for-pin replacement for µA709, µA748, or LM101
  • Compensated with a single capacitor PIN CONFIGURATIONS 4 5 OFFSET NULL INVERTING INPUT NON–INVERTING INPUT FREQ. COMP. OUTPUT OFFSET N, FE Packages
  • Same low drift offset null circuitry as µA741
  • Small-signal bandwidth 1MHz
  • Large-signal bandwidth 500kHz
  • True op amp DC characteristics make the 531 the ideal answer to all slew rate limited operational amplifier applications
