RIAA Preamplifier (single power supply operation)
Note) R1 and R2 are resistances for setting operational amplifier bias.
Set R1 and R2 so that VEXT=2.0V to 6.0V.
(Recommended Voltage VEXT=4.5V)
s How to Apply External to the AN6550
1. The AN6550 is an operational amplifier with a phase
compensation circuit built-in, allowing low voltage oper-
ation, and its current consumption and bandwidth can be
changed by applying external bias to it.
2. As shown below, applys bias voltage to 2 VEXT pin of the
AN6550 allows the AN6550 to be handled in the very
same way as the AN6551, except for pin connection.
Set VEXT >=VEE+1V.
