8 / 10 page Applications Information (Continued) When adjusted for maximum boost in the usual application circuit, the LM1036 cannot give additional boost from the loudness control with reducing gain. If it is required, some additional boost can be obtained by restricting the tone con- trol range and modifying C t,Cb, to compensate. A circuit il- lustrating this for the case of bass boost is shown in Figure 13. The resulting responses are given in Figure 14 showing the continuing loudness control action possible with bass boost previously applied. USE OF THE LM1036 ABOVE AUDIO FREQUENCIES The LM1036 has a basic response typically 1 dB down at 250 kHz (tone controls flat) and therefore by scaling C b and C t, it is possible to arrange for operation over a wide fre- quency range for possible use in wide band equalization ap- plications. As an example Figure 15 shows the responses obtained centered on 10 kHz with C b=0.039 µF and C t=0.001 µF. DS005142-16 FIGURE 13.
