The OPA2237UA is a dual small size Operational Amplifier features low offset voltage, low quiescent current, low bias current and a wide supply range. Dual version has identical specifications for maximum design flexibility. It is ideal for single-supply, battery-operated and space-limited applications, such as PCMCIA cards and other portable instruments. Dual design features completely independent circuitry for lowest crosstalk and freedom from interaction.
The LM358M/NOPB is a high-gain low power dual Operational Amplifier consists of two independent operational amplifiers which were designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage. Application areas include transducer amplifiers, DC gain blocks and all the conventional op-amp circuits which now can be more easily implemented in single power supply systems. The LM358 series internally frequency compensated amplifier can be directly operated off of the standard 3.3V power supply voltage which is used in digital systems and will easily provide the required interface electronics without requiring the additional ±15V power supplies.
