The OPA377 family of operational amplifiers are wide-bandwidth CMOS amplifiers that provide very low noise, low input bias current, and low offset voltage while operating on a low quiescent current of 0.76mA (typ). Op-amps and CMOS Scaling The Operational Amplifier (op-amp) is a fundamental building block in Mixed Signal design. In such circuits two stage op-amps are used. Measuring 2.9 mm x 4.0 mm x 0.9 mm, the new device comes in an MSOP8 package and has a wide operating voltage … gain while sinking is higher than most CMOS op amps, due to the additional gain stage; however, under heavy load (600Ω) the gain will be reduced as indicated in the Electrical Characteristics. These low power op amps benefit from STMicroelectronics 5 V CMOS technology and offer an excellent speed/power consumption ratio (150 kHz typical gain bandwidth) while consuming less than 14 μA at 5 V. The OA1MPA, OA2MPA, OA4MPA series also feature an ultra-low input bias current. Open-loop gain is the gain of the op-amp without positive or negative feedback and for such an amplifier the gain will be infinite but typical real values range from about 20,000 to 200,000. systematic errors is channel length modulation.
