Ordering number : EN4530A
Monolithic Linear IC
LA3235W
1.5 V Record Preamplifier
Overview
The LA3235W is a single-chip record system IC for use in
1.5 V headphone stereo products. While previous
recording systems were implemented using a dedicated
tape drive, by using the LA3235W, such a system can be
implemented by adding electronic switching to a
playback-only tape drive. Additionally, a compact
record/playback system can be implemented with just two
chips by combining this IC and the LA4590W 1.5 V
preamplifier/power amplifier IC
