Figures 1-17 and 1-18 show a typical application circuit and pin descriptions, respectively for a MAX696. The IC is similar to that described for Figs. 1-J through 1-N, but with added (or combined) features. Use the equations shown in Fig. 1-M to calculate the values for the resistors at the PFI and LLIN inputs (except use a threshold of 1.3 V, instead of 2.54 V). Figures 1-19, 1-20, 1-21, 1-22, and 1-23 show the reset timing, watchdog and reset timeout selection, calculations and connections for adding hysteresis, circuit for disabling the watchdog under program control, and circuit for selecting watchdog timeout, respectively.

Basic_inverting_amplifier

Published:2009/7/23 21:34:00 Author:Jessie

This circuit shows an LM107 that is connected in the classic inverting-amplifier configuration, where VOUT is opposite to VIN (if VIN goes positive, VOUT goes negative, and vice versa). The amplitude of the output depends on the ratio of R1 and R2 (within the limits of the supply voltage), and R3 is selected to equal the parallel resistance of R1 and R2.   (View)
