Circuits sometimes need a gain-of-one buffer to lower output impedance and prevent the load from interfering with the previous stage. For an application involving a 1.5-MHz, low-power transmitter and ...

Figure 8 shows the circuit diagram of a preamplifier with a transistor at the input and output buffer with QOAs. Figure 8. Circuit of preamplifier with NPN transistor and output buffer with one QOA ...

Developed to help simplify VCO module designs, the UPA861TD combines the companyÕs high performance NE894 oscillator chip with its NE687 buffer chip into a single miniature package. The twin ...
