For low-noise amplifier OP amplifier RIAA compensation


Posted on Mar 28, 2007

Common telecoil is MM formula (magnetic-acting), about 600 in order to take the received signal, should reduce the impedance in the high segment, in parallel with 150pF input p

ower capacity o OP27 is a low-noise, high-precision amplifier OP, which the input offset voltage is small, drift is small, so the feedback loop DC coupling, to improve the low-frequency characteristics. Because the compensation circuit is determined by three time constants, so CR values can have a variety to choose from.
