why should be improved DDR2 memory to DDR3

DDR3 offers a substantial performance improvement over previous DDR2 memory systems New DDR3 features all transparently implemented in the memory controller, improve the signal integrity characteristics of DDR3 designs soo that higher performance is achieved without an undue burden for the system designer. If proper consideration is given to any new DDR2 memory design it […]

3W Audio Amplifier Circuit using TA7230P

High voltage op amp

high voltage op amp using UA741 The op-amp UA741 is wired to operate in three frequency ranges- high, medium and low. The circuit is designed such that the circuit produces +/-20 dB boost or attenuation for 50Hz,1KHz and 10Khz by varying POT’s R2. The maximum amplification for any of these bands at maximum supply voltage […]

4 channel audio splitter / Audio Distribution Amplifier 4558

The three channel output distribution amplifier uses 4558. The first stage is resistor coupled with a 33k.… Each output stage independently drives an amplifier through the 50 µF output capacitor to the 4k7 kΩ load resistor.
