The single/dual power supply converter circuit

Published:2011/6/23 21:55:00 Author:Seven | Keyword: power supply, converter

The single/dual power supply converter circuit
TDA2030 is an efficient computing amplifier. With its complementary input stage, we can convert the single pole power supply into two dual pole power supplies that the low-power circuits need. In the circuit, the resistors of R1 and R2 with the same resistance compose a voltage distributor which makes the upper and lower part have the same voltage. The central point of the distributor is connected with the non-inverting phase input terminal of the amplifier, and the op-amp is assembled into a voltage follower which makes the LEV of O' and O terminal the same. And O' is a vain point, so it has to be separated from the power supply.   (View)
