I am trying to use an lm 2917 (8 pin) as a basic freq to voltage converter. http://www.ti.com/lit/ds/symlink/lm2907-n.pdf I set up the circuit in the datasheet (page 10 1st diagram), using 12V for Vcc and a 250mV (peak to peak) 600Hz square wave offset so that the minimum amplitude of the wave was at 0V as the frequency input. This setup worked but when I increased the amplitude of the square wave to 1.5V (with corresponding change in offset) it broke the chip. The datasheet says the input voltage can be a max of +-28V, so I'm a bit confused at why it broke. Is there a way I can get it to work with a larger amplitude wave?
