SUMMARY
The LM319 high-speed comparator can accept negative supply voltages, allowing for configurations such as ±18 V or +11 V to -25 V. It is possible to produce a square wave oscillating between 10V and -10V, but the output will not reach the full ±10 V peak-to-peak due to the maximum rating of 16 V between ground and Vcc. To achieve a symmetrical output around 0 V, one can set Vs+ to +5 V, ground to -5 V, and Vs- to -6 V. However, for generating a precise ±10 V output, a different operational amplifier (op amp) is recommended.
