0.1V | 2.4V | –2.3V | 2.3V | 2.7V | 0V | 2.5V |
This circuit converts a single ended input of 0.1V to 2.4V into a differential output of ±2.3V on a single 2.7V supply. The input and output ranges can be scaled as necessary as long as the op amp input common-mode range and output swing limits are met.
