ROHM BA3126N, BA3126F Datasheet
Audio ICs
2-channel head switch for radio
cassette recorders
BA3126F / BA3126N
The BA3126F and BA3126N are dual-channel tape head switching ICs designed for use in radio cassette players.
These ICs are designed to withstand voltages of up to 120V
recording. Both devices have two channels, and are ideal for use in radio-cassette players.
The package types are 14-pin SOP for the BA3126F, and 9-pin SIP for the BA3126N.
Applications
Radio-cassette players
