WebApr 7, 2015 · For narrow temperature range applications, you’re better off using a well-trimmed device such as the OPA376 instead of the OPA333, for example. The difference in the initial offset voltage is 15µV, but the difference in input bias current is 190pA! WebThe output offset storage technique limits the maximum gain of the ampliﬁer. If a high gain is needed, storing the offset at the input storage capacitance would be a better solution. Figure 2.3 shows the basic principle of input offset storage tech-nique [2]. In the auto-zeroing phase when CK is high, the output and input of the

WebThe output voltage caused by the input offset voltage can be computed with our basic gain equation. FIGURE 10.4. The input offset voltage contributes to the DC offset voltage in the output of an op amp. The manufacturer's data sheet for a standard 741 lists the worst-case value for input offset voltage as 6 millivolts. Weboﬀset to balance the oﬀset of the OA. Tune the potentiometer until the oﬀset on the output disappears. Method 2: Internal Balance Trim Use the “offset null” or “balance” pins provided by most OAs (e.g., OAs shown in Figure A.1). 1. Before you wire your integrator, temporarily short the input pins of the OA together (it may be
