  • 6 MHz Gain Bandwidth
    • Dedicated external output (OPAxOUT)
    • Multiple noninverting input pins available (OPAxIN+)
    • Multiple inverting input pins available (OPAxIN-)
  • Programmable Gain Options Using Built-in Internal Resistor Ladder
  • Configurable Negative Source Selections
  • Input Offset Voltage Calibration
    • User programmable calibration
    • Self-calibration
