The comparators (output = ‘1’, when input ≥ 0 and output = ‘0’, when input < 0), exclusive-OR gate and the unity gain low-pass filter given in the circuit are ideal. The logic output voltages of the exclusive-OR gate are 0 V and 5 V. The cutoff frequency of the low-pass filter is 0.1 Hz. WebBest, Paul. Bala Ravi over 5 years ago. TI__Expert 6625 points. Hi Mike, You can use TLV6001 as a comparator. Since your have a low frequency input, you shouldn't see much lag using TLV6001. But if you plan on using higher frequency input, I would recommend looking into other devices because you will be limited due to slew rate using TLV6001.
