Unformatted text preview: L isolates them, and v L does not depend upon R L . (a) (b) Fig. 21-6: An op amp used as an inverting amplifier. On the right, we show the dependent source model of an inverting amplifier. Fig. 21-8: A voltage divider with an inverting amplifier used to convert the 15 V to 5V. Fig. 21-7: A voltage divider used to step the voltage down from 15 V to 7.5V.
