8 / 23 page LM1036 SNAS525C – JAN 1995 – REVISED APRIL 2013 www.ti.com APPLICATIONS INFORMATION OBTAINING MODIFIED RESPONSE CURVES The LM1036 is a dual DC controlled bass, treble, balance and volume integrated circuit ideal for stereo audio systems. In the various applications where the LM1036 can be used, there may be requirements for responses different to those of the standard application circuit given in the data sheet. This application section details some of the simple variations possible on the standard responses, to assist the choice of optimum characteristics for particular applications. TONE CONTROLS Summarizing the relationship given in the data sheet, basically for an increase in the treble control range Ct must be increased, and for increased bass range Cb must be reduced. Figure 14 shows the typical tone response obtained in the standard application circuit. (Ct=0.01 μF, Cb=0.39 μF). Response curves are given for various amounts of boost and cut. Figure 14. Tone Characteristic (Gain vs Frequency) Figure 15 and Figure 16 show the effect of changing the response defining capacitors Ct and Cb to 2Ct, Cb/2 and 4Ct, Cb/4 respectively, giving increased tone control ranges. The values of the bypass capacitors may become significant and affect the lower frequencies in the bass response curves. Figure 15.
