8. C volume control stages designed for TV and monitors but also suitable for battery fed portable recorders and radios In conventional DC volume control circuits the control or input stage is AC coupled to the output stage via external capacitors to keep the offset voltage low The two DC volume control stages are integrated into the input stages so that no coupling capacitors are required and a low offset voltage is still maintained The minimum supply voltage also remains low The BTL principle offers the following advantages e Lower peak value of the supply current e The frequency of the ripple on the supply voltage is twice the signal frequency Consequently a reduced power supply with smaller capacitors can be used which results in cost reductions 1997 Jul 15 PGND1 OUT1 OUT2 n c PGND2 OUT2 MSA719 2 Fig 2 Pin configuration For portable applications there is a trend to decrease the supply voltage resulting in a reduction of output power at conventional output stages Using the BTL principle increases the output power The maximum gain of the amplifier is fixed at 40 5 dB The DC volume control stages have a logarithmic control characteristic Therefore the total gain can be controlled from 40 5 to 33 dB If the DC volume control voltage falls below 0 4 V the device will switch to the mute mode The amplifier is short circuit protected to ground Vp and across the load
