Low power dual bipolar operational amplifiers
Description
MC33172 MC35172
Low power dual bipolar operational amplifiers
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
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.
