Web6 de jun. de 2024 · The offset should be dominated by the bias current x 1M, approximately. Edit: Given the very low typical bias current of the TSV992IST op-amp you are using, the offset will be dominated by Vos of the op-amp. Output offset (relative to junction of R5/R6) should be significantly less than 10mV at or relatively near room temperature with that …

In signal processing, when describing a periodic function in the time domain, the DC bias, DC component, DC offset, or DC coefficient is the mean amplitude of the waveform. If the mean amplitude is zero, there is no DC bias. A waveform with no DC bias is known as a DC balanced or DC free waveform.
