MC33172D STMicroelectronics

MC33172 MC35172 Low power dual bipolar operational amplifiers Features Good consumption/speed ratio: only 200 A for 2.1MHz, 2V/s Single (or dual) supply operation from +4 V to +44V (2V to 22V) N Wide input common mode mode voltage range DIP8 including V - CC (Plastic package) Low level output voltage close to V - : CC 100 mV typical Pin-to-pin compatible with standard dual operational amplifiers Description The MC3x172 series are dual bipolar operational D amplifiers offering both low consumption SO-8 (200 A/Amp) and good speed (2.1 MHz, 2 V/s). (Plastic micropackage) Moreover, the input common mode range extends down to the lower supply rail, allowing single supply operation from +4 V to +44 V. 1 8 V Output 1 CC Inverting Input 1 2 7 Ouptut - + Non-inverting Input 1 3 - 6 Inverting Input 2 V + CC45 Non-inverting Input 2 Pin connections (top view) July 2008 Rev 2 1/9 www.st.com 9Circuit schematics MC33172 MC35172 1 Circuit schematics Figure 1.
