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 9 gives the circuit diagram of a buffer with inverting and non–inverting outputs. Figure 9. Circuit of buffer and inverter with NPN transistors and output buffer with two QOA (The OAs are ...

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 ...
