Hi team,
my customer is doing above circuit. And VIN=5V, VREF is 2.5V, Sig+ is a sine wave with 2Vpp and 1k frequency.
But the out(before C83) is distorted as below pictures. TLV333 is rail to rail devices. In my understanding, the output should not distorted, right?
In addition to showing the input signal (right on pin 3), it would be helpful to show the impedance to the right of C83 (Zc=~34ohm@1kHz) to eliminate the possibility that the load pushes the output stage of TLV333 to sink current above its short-circuit level of +/-5mA.
