Sales Briefcase
  • The MC3x172 series are dual bipolar operational amplifiers offering both low consumption (200 µA/Amp) and good speed (2.1 MHz, 2 V/µs).

    Moreover, the input common mode range extends down to the lower supply rail, allowing single supply operation from +4 V to +44 V.

    Key Features

    • Good consumption/speed ratio: only 200 µA for 2.1 MHz, 2 V/µs
    • Wide input common mode mode voltage range including VCC-
    • Single (or dual) supply operation from +4 V to +44 V (±2 V to ±22V)
    • Pin-to-pin compatible with standard dual operational amplifiers
    • Low level output voltage close to VCC- : 100 mV typical
