BD3881FV
BD3881FV is Audio sound controller manufactured by ROHM.
Feature
:
１．Dual built-in recording and playing preamplifiers for cassette tapes Less external ponents allows a pact size of the set.
２．The shock sound at power-ON/OFF is absorbed by both power sources. The reference voltage of signal systems is designed to be a ground level so that low offset voltage and low noise are achieved.
