Tone Characteristic (Gain vs Frequency) Figure 20. Loudness Compensated Volume Characteristic Figure 21 and Figure 22 illustrate the loudness characteristics obtained with Cb changed to Cb/2 and Cb/4 respectively, Ct being kept at the nominal 0.01 μF. These values naturally modify the bass tone response as in Figure 15 and Figure 16. With pins 7 (loudness) and 12 (volume) directly connected, loudness control starts at typically −8 dB volume, with most of the control action complete by −30 dB. Figure 23 and Figure 24 show the effect of resistively offsetting the voltage applied to pin 7 towards the control reference voltage (pin 17). Because the control inputs are high impedance, this is easily done and high value resistors may be used for minimal additional loading. It is possible to reduce the rate of onset of control to extend the active range to −50 dB volume control and below. The control on pin 7 may also be divided down towards ground bringing the control action on earlier. This is illustrated in Figure 25, With a suitable level shifting network between pins 12 and 7, the onset of loudness control and its rate of change may be readily modified. 10 Submit Documentation Feedback Copyright © 1995–2013, Texas Instruments Incorporated Product Folder Links: LM1036 |
