APPLICATIONS INFORMATION WIDEBAND VOLTAGE FEEDBACK OPERATION The OPA642’s combination of speed and dynamic range is easily achieved in a wide variety of application circuits, providing that simple principles of good design practice are observed. For example, good power supply decoupling, ...

DAC TRANSIMPEDANCE AMPLIFIER High frequency DDC DACs require a low distortion output amplifier to retain their SFDR performance into real-world loads. A single-ended output drive implementation is shown in Figure 4. In this circuit, only one side of the complemen- ...

In the inverting configuration, an additional design consid- eration must be noted. R becomes the input resistor and G therefore the load impedance to the driving source. If imped- ance matching is desired, R may be set equal to the ...

while in the inverting F G configuration this is just R (Figure 1). Increasing output F voltage swing increases harmonic distortion directly. A 6dB increase in output swing will generally increase ...

This optimum turns ratio is calculated by N Nearest Integer OPT N This optimum will depend strongly on the amplifier and configuration selected 7V/V [16.9dB ...

Note that it is the power in the output stage and not into the load that determines internal power dissipation worst case example, compute the maximum T OPA642N (SOT23-5 package) in the circuit of Figure 1 operating at ...

Socketing a high speed part like the OPA642 is not recommended. The additional lead length and pin-to-pin capacitance introduced by the socket can create an ex- tremely troublesome parasitic network which can make it almost impossible to achieve a ...
