8.4.7 Noise

The VCA824 offers 6 nV/√Hz input-referred voltage noise density at a gain of 10 V/V and 2.6-pA/√Hz input-referred current noise density. The input-referred voltage noise density considers that all noise terms (except the input current noise but including the thermal noise of both the feedback resistor and the gain resistor) are expressed as one term.

This model is formulated in Equation 4 and Figure 68.

A more complete model is shown in Figure 69. For additional information on this model and the actual modeled noise terms, please contact the High-Speed Product Application Support team at www.ti.com.
