Pursuing perfection
How the combination of low power, small size and high precision is moving op amp technology nearer to an ideal device. By Brian Black.
Although by definition unachievable, the ideal op amp provides a complete collection of specifications to offer as targets for analogue designers. Every application requires a different combination of specifications and the number of op amps continues to expand to fit those needs. Using novel techniques, these products are getting closer to the ideal, delivering better performance whilst operating on lower supply voltages and consuming less current.
