General Description

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.

Overview

MC33172 MC35172 Low power dual bipolar operational amplifiers.

Key Features

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