TDA7316
Key Features
- The first stage is a volume control. The control range is 0 to -17.625dB with 0.375dBstep. The very high resolution (0.375dB step) allows the implementation of closed loop amplitude control system pletely free from any acustical effect (stepping variation and pumping effect). The volume control is followed by a serial four bands equalizer. Each filtering cell is the biquad cell shown in fig. 1 The internal resistor string is fixing the boost/cut value while the buffer makes the Q (quality factor) and central frequency, set by external ponents, fully indipendent from the internal resistors. Each filtering cell is realized using only 4 external ponents (2 capacitors and 2 res
