Question

For the circuit below, the output is at 15 V and the input voltage is at +2 V if the input voltage is gradually lowered to -2 V, at what input voltage does the output switch from +15 V to-15 V (to 1 % accuracy)? The op-amp has rail-to-rail swing, and a gain-bandwidth product of 3 MHz. The resistors used are r1 -1.5 k ohm and r2 22.8 k ohm r2 Vin 2 +2 V +15 V r1 f 1 kHz out Answer: For the circuit below, the output is at-15 V, and the input voltage is at -2 V. if the input voltage is gradually raised to 2 V, at what input voltage does the output switch from -15 V to +15 V (to 1 % accuracy)?
