  • Supports switching frequencies up to 125 kHz.
  • Wide common-mode voltage:.
  • Operational voltage:.
  • 5 V to +110 V.
  • Survival voltage:.
  • 20 V to +120 V.
  • Bidirectional operation.
  • High small signal bandwidth: 1.1 MHz (at all gains).
  • Slew rate: 8 V/µs.
  • Step response settling time to 1%: 1 µs.
  • Excellent CMRR.
