Low power and quick accurate low-voltage op-amps from Maxim

Maxim has quietly released a couple of op-amp families, one very low power and the other blending high speed, precision and low noise. MAX40023 and MAX40024 are single and dual amplifiers that will run from 1.6 to 3.6V, typically for 17μA per channel. A shut-down pin typically takes this to 55nA. Both inputs and outputs swing ...
