DESCRIPTION
The LC506 and LV506 are class A non-inverting preamplifiers
with 40 dB feedback controlled, stabilized gain.
Gain trim is provided at pin 1, which simultaneously affects
both gain and output noise, independent of the main volume
control.
A voltage regulator is built on-chip to supply the amplifier and
electret microphone with precision reference voltage. A typical
regulator voltage for the LC506 is 0.95V, while it is 0.90V for the
LV506. This regulator feature of the LC506 allows it to be used
with the high power LD549 to provide increased supply rejection
during transient drops in supply voltage, caused by high
current peaks in the LD549.
Both LC506 and LV 506 devices are capable of operating from
a supply voltage of 1.55 VDC while continuously providing
80 dB of regulator supply rejection.
