1. TL064CD Substitution Conclusion
The TL064CD matches the original TL064BIDT in key AC performance (e.g., bandwidth, slew rate) and quiescent current. However, its supply voltage range (10 V to 30 V) is narrower than that of the original (6 V to 36 V), and its input offset voltage (3 mV) is slightly higher than the original’s 2 mV. If the original system operates from a single low-voltage supply (e.g., below 10 V) or is used in high-precision DC amplification, the TL064CD may not be a direct substitute, potentially causing malfunction at low voltage or a slight degradation in DC accuracy. In typical dual-supply applications such as ±5 V to ±15 V general-purpose audio or filtering circuits where offset voltage is not critical, it can serve as a functionally compatible replacement.
2. TL064ACD Substitution Conclusion
The TL064ACD shares identical parameters with the TL064CD, and the substitution conclusion is essentially the same: it is suitable for applications where the original supply voltage exceeds 10 V and input offset voltage requirements are relaxed. Note that the “A” suffix typically indicates tighter offset voltage screening; however, the specified offset voltage here is 3 mV—the same as the TL064CD—showing no advantage from the “A” grade. Therefore, in practice the TL064ACD should be considered equivalent in performance to the TL064CD, and the same attention must be paid to supply‑voltage compatibility and DC‑precision suitability when substituting.
